How Much Do Solar Panels Cost
Prices for solar panels has decreased substantially in the last couple of years. This is great because, combined with the 30$ federal solar Investment Tax Credit and other applicable incentives, NOW is the best time ever to invest in a solar power system. And, consider this: a solar power system costs about the same as a mid-sized car!
How Do Solar Panels Work With Batteries
With solar panels, you use the electricity as its generated. However, solar batteries are now available which store the power your panels have produced during the day so you can use it later.
There are different types of solar batteries, all with different features and capabilities. Some are about the size of a car battery, while others can be as large as a generator or a washing machine.
Most people who have solar panels installed go without a battery as theyre happy to revert back to the power from the national grid when their panels arent generating electricity themselves. Its usually people who are determined to live off-grid who decide to use solar batteries.
Lets Say That Youve Decided Not Only To Go Solar But You Want To Go All
If youâve used our solar calculator or looked at the map of solar homes around you, youâll know that going solar is pretty easy and increasingly common. As the price continues to drop, it becomes affordable for more people. But what if you want to go completely solar? What if you donât want to use any fossil fuels at all in your home?
Yes, itâs possible for solar panels to supply all of the electricity your home needs. The first step is to maximize your energy efficiency with insulation, air sealing, and efficient appliances. Then, move off fossil fuel heating to electric heat pumps, and replace gas cooking and water heating with electric. Once youâve done that, a correctly sized photovoltaic system can be used to power everything in your home. But does it make sense?
This guide will explain how you can go completely solar in your home. But before we launch into it, letâs clarify what it really means when we talk about making your house completely solar.
- Want to generate all of your current electricity usage with solar, but leave some appliances, like your stove and furnace, using fossil fuels?
- Or do you want to move 100% of your home energy use to solar? This is called net zero.

How Do Solar Panels Work For Your Home
Solar energy is growing worldwide as more and more countries switch on to the need for renewable energy types. The sun shines every day and amazingly the energy it provides the earth for one hour could meet global energy needs for a whole year.
However, we are only able to harness 0.001 per cent of that energy, so we simply have to utilise as much of the power that this incredible star at the centre of the Solar System offers as we can.
The use of solar panels dates back to 1839 when Alexandre Edmond Becquerel discovered the photovoltaic effect, explaining how electricity can be generated from sunlight. Clever boy.
The cost of solar energy has dropped in recent years as the clamour for green energy options grow and technical efficiencies improve.
Today, solar panels are a viable way of cutting your electricity bills as well as allowing you to do your bit in the battle to live self-sustainably, or at least reduce the carbon footprint in your home. Its an easy way to help save the planet, so youre doing right by your children and your childrens children too.
Thecost Of The Wrongful Disposal Of Solar Panels
In November 2018, Japanâs Environmental Ministrywarned that the number of solar panels that will become waste every year wouldrise from 10k to 800k by 2040. The problem? Japan has no plans in place tosafely dispose of the panels people will be throwing away as they wear out.
The problem is larger than just the sheer number ofpanels that will be filling up our landfills. Solar panels create three-hundredtimes more toxic waste per unit of energy than nuclear power plants, astartling revelation.
Not only is the world faced with toxic waste enteringour water supply from the wrongful disposal of solar panels, but countries likeChina, India, and Ghana with communities that live near waste dumps whereelectronics are salvaged for their valuable copper wiring burn the devices toget to the wiring. Burning releases fumes from the plastics resulting in smokethat contains toxic fumes known to be carcinogens and to cause birth defectswhen breathed in.

Solar Power Is Here To Stay
Solar energy via the use of solar panels is not goingto go anywhere anytime soon. In fact, the manufacture of solar panels isprojected to more than triple in the next ten years. This means that morepeople are thinking green and are wanting to reduce their dependence on fuelsthat are not renewable.
As technology advances, going green will soon become the norm instead of the exotic solution to global warming.
Recyclingsolar Panels For Business Use
Businesses, especially in the manufacturing realm, arebeginning to find the cost savings of using solar panels in their plants andoffice spaces. Especially in areas where the cost of electricity from traditionalsources, the appeal of solar power is growing.
Yet, with the increase in the use of solar panelscomes the huge problem of knowing what to do with them when they are done beinguseful. Of course, recycling is the answer, but businesses are finding itcostly to search for and hire recycling businesses that handle the toxic wasteof solar panels.
The answer to getting more businesses to recycle theirsolar panels is to offer monetary incentives in the form of tax incentives andmonetary rewards for recycling.
The Formationof A Regulatory Organization
One possible solution that is not currentlypolitically correct is the formation of a regulatory organization to overseethe disposal of solar panels. The United States already has such anorganization to watch over nuclear waste, yet as deadly a problem as nuclearwaste is becoming, there is far less of it than solar panel waste.
A regulatory organization could make rules and offerlicenses and incentives on a federal level that allows for the success ofstopping solar panels from ending up in landfills and finding better andgreener solutions.
Selling Your Current Property
Before putting your home on the market, the decision of whether to bring the solar panels or sell them along with the house must first be determined. If you choose to leave them, having a home on the market with solar panels is an excellent selling point for those interested in a green lifestyle, which means you can raise the asking price.
If you havent decided about the panels and put the home on the market and its sold, unfortunately, the panels are no longer yours to take. The solar panel system is considered a fixture and remains with the home.

What Does A Solar Inverter Do
A solar inverter takes the DC electricity from the solar array and uses that to create AC electricity. Inverters are like the brains of the system. Along with inverting DC to AC power, they also provide ground fault protection and system stats, including voltage and current on AC and DC circuits, energy production and maximum power point tracking.
Central inverters have dominated the solar industry since the beginning. The introduction of micro-inverters is one of the biggest technology shifts in the PV industry. Micro-inverters optimize for each individual solar panel, not for an entire solar system, as central inverters do.
This enables every solar panel to perform at maximum potential. When a central inverter is used, having a problem on one solar panel can drag down the performance of the entire solar array. Micro-inverters, such as the ones in SunPower’s Equinox home solar system, make this a non-issue. If one solar panel has an issue, the rest of the solar array still performs efficiently.
Order Of Module Connection
Module electrical connections are made in series to achieve a desired output voltage or in parallel to provide a desired current capability of the solar panel or the PV system. The conducting wires that take the current off the modules are sized according to the current rating and may contain silver, copper or other non-magnetic conductive transition metals. Bypass diodes may be incorporated or used externally, in case of partial module shading, to maximize the output of module sections still illuminated.
Some special solar PV modules include concentrators in which light is focused by lenses or mirrors onto smaller cells. This enables the use of cells with a high cost per unit area in a cost-effective way.
Solar panels also use metal frames consisting of racking components, brackets, reflector shapes, and troughs to better support the panel structure.
Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multi-junction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells. The Spectrolab scientists also predict that concentrator solar cells could achieve efficiencies of more than 45% or even 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions.

How Many Solar Panels Are Needed To Power My Home
The average home in the U.S. uses 10,400 kWh of electricity per year. If you install the average 250-watt solar panel, youd need around 28-34 solar panels to generate enough energy to power your entire home.
However, unlike the traditional utility grid, which is automatically connected to your home during construction, solar panel installation is a highly individualized process something which also drives its price. We recommend taking these three steps to determine whether solar panels could be a good fit for you:
Lets try some basic math:
- 11,000 kWh of annual electricity usage / 1.31 = 8,396.9
- 8,396.9 / 250 = 33.58 » 34 panels.
While this estimate should not replace a professional evaluation, it can provide a useful rough idea to indicate the feasibility of solar panel installation for your house.
Use It In Emergencies
We live in a world where anything can happen to you anytime. You should always be prepared with the right equipment, and the energy source is one of the factors that may have a big difference when you are in trouble.
Carrying a portable solar panel while travelling in a remote area would give you the advantage of an immediate power source.
You can charge your phone use it to light up the area with the small bulb, set the emergency kit, etc.
In places where an earthquake, hurricane, tornado are common, using the portable solar panel in such a location would give you instant support and connectivity to the communication service.

How Many Solar Panels Are Needed To Charge A 12v Battery
A single 200-watt panel should charge a 12v, 100ah battery in a day. Alternatively, two 100-watt panels or four 50-watt panels will do the same.
It is possible to use smaller solar panels a single 100-watt panel for example but this will just increase the time it takes for your battery to charge.
If youre using your battery as a backup or using much less than a full battery charge in a day, a 100-watt panel is certainly large enough to get the job done.
How Do Solar Panels Work On Houses
Solar panels work by absorbing sunlight with photovoltaic cells, usually after being placed on the roof of a house. The panels convert this sunlight into direct current energy which travels inside the house to an inverter, which in turn converts it to alternating current energy, which then flows through the homes electrical panel powering any appliances with electricity. Any excess electricity will be sent off to the electric grid, which in turn provides you with the electricity needed if you use more than the panels create.
Thats a lot to take in all in one go, so heres your four-step overview:

What Are The Benefits Of Using Portable Solar Panels
There are several reasons why the portable solar panel has become the first choice of people who want to begin their journey to the renewable energy source.
The fundamental reason why people shift to the portable solar panel is safety. These panels are safe to use in all kinds of environments.
Compared to the large solar panel, which can produce a high voltage current. Handling those big solar panels would be life-threatening.
You would not like anyone touching those high voltage panels or the connection in your home. The portable solar panels are known for low voltage current.
However, they are also dangerous to handle, but most of them are very safe and build with the material covering most of the panel to carry the panel with you comfortably.
Here are some of the benefits people enjoy using the portable solar panel to generate renewable energy.
Why Not Go Off
People who want to get off fossil fuels completely and ensure that only clean energy passes through their wires might be tempted to go off-grid completely. And that certainly is an option, but it can be a very costly one.
Though going solar has never been less expensive than it is now, its still a financial commitment and choosing an off-grid solar setup can get very expensive. Even a small off-grid solar system with battery storage will cost many thousands of dollars more than a grid-tied system, simply because the hardware needed to make it all work costs so much.
In addition, off-grid battery storage needs to be able to provide the correct amount of electricity you might need over the course of three cloudy, snowy days during the coldest part of the winter wherever you live. Its overkill in the sunnier months, but you dont want to get caught without enough power, and then have to resort to a fossil fuel generator. That puts you right back at square one.

Solar Power For The Home: Benefits
A significant benefit to PV installation is a lower energy bill, but the magnitude of this benefit depends on the amount of solar energy that can be produced given the available conditions and the way in which utilities charge for electricity.
The first consideration is the solar irradiation levels available in the home’s geographical location. When it comes to using solar panels, being closer to the equator is generally better, but other factors must be considered. The National Renewable Energy Laboratory produces maps for the U.S. showing solar irradiation levels the tools on its website provide detailed solar information for specific locations within the U.S.
Similar maps and data are available in other countries as well, often from government environmental agencies or renewable energy organizations. Equally important is the home’s orientation for rooftop arrays, a south-facing roof without trees or other objects obstructing sunlight maximizes the available solar energy. If this is not available, panels can be mounted on external supports and installed away from the house, incurring additional costs for the extra hardware and cables.
The final benefit is the potential effect on a home’s value due to the addition of a solar array. In general, it is reasonable to assume that solar panels would raise the value of most homes.
Whatnot To Do With Broken Or Old Solar Panels
Currently, in the United States, only two states haveany regulations regarding the disposal of solar panels. This is a sobering factas solar panels that once were used to generate electricity can, in fact, endup in landfills where they become a poisonous danger to the world.
Once solar panels have passed their usefulness, theworst thing a homeowner or business owner can do is to relegate them to alandfill. Unfortunately, this is the fate of a significant percentage of solarpanels.
Even worse, some businesses who claim to recycle solarpanels themselves actually try to mitigate the inflated cost of sorting thematerials by shipping them to poor countries where children and the poor areforced to pick through the waste. In the process, these people are exposed tocarcinogens and other unhealthy chemicals.
Bottom line? Do not dispose of solar panels by eitherthrowing them into a landfill or by allowing a business that has not beenwell-vetted to take them.
