What Is The Best Way To Store Solar Energy
Electrochemical energy storage, also called batteries, is the most commonly used energy storage device at homes. The two commonly used battery technologies are lead-acid and lithium-ion. Each of them has its own pros and cons.
Lead-acid batteries are the world`s most widely used battery technology.
Some of the key benefits of this technology are relatively low cost, reliability, and service life. The technology is uncomplicated and mature. Some of the drawbacks of this battery technology include slow charging, limitation on depth of discharge, and a limited number of charge-discharge cycles.
Lithium-ion batteries, on the other hand, are one of the most widely utilized energy storage technologies for portable electronics today.
The key characteristics of the battery include high energy density and long cycle life.
How Much Will Solar Panels Cost For Your Specific House Based On Your Location And Energy Use
While average price is interesting, your house is unlikely to be average. What you really need to know is how much solar panels will cost to install on your particular house given its location, electricity usage, and what kind of savings and payback period can you expect.
SolarReviews has developed a very sophisticated solar panel cost and savings estimator that can answer this question for you based on your local weather, your local utility rates and the prices of your local solar companies.
Calculate how much solar panels will cost for your house based on your location and current electric bill
We get it – $12,000 isnt pocket change. Luckily, there are many zero-down solar financing options available, like solar loans, that allow you to go solar and start saving the minute the panels are turned on, without having to worry about any large upfront costs. We recommend solar loans rather than leases because you keep the solar tax credits.
With solar leases the leasing company gets the tax credits and, if you sell your home, the buyer needs to accept assignment of the solar lease. With a solar loan you own the system and so this is not necessary.
Note for new solar enthusiasts: Solar system capacity is measured in watts and kilowatts. One kilowatt is 1,000 watts. The kilowatt rating of a system is a measurement of the maximum generation capacity of the system.
Solar : How Solar Energy Works
Have you ever looked at the solar panels on roofs and wondered exactly what they do, and how? Well, those hi-tech expanses of shimmering glass are actually just one component in a complex network that harnesses the suns renewable energy to deliver electricity to the home within.
Lets take a simple, step-by-step look at how solar power works.

Tip : Determine The Battery Capacity
The most efficient way to size the battery system is to size it based on the daily energy demand. For example, if the daily energy demand is 20 kWh, it is advisable to install a 20 kWh battery system.
An alternative to this is to estimate the excess solar production that will be generated during the daytime and size the battery bank for this excess solar production.
It will be difficult to get this number right and the worst-case scenario is an undersized battery system.
It is important to note that although a battery system is expensive, having a slightly larger battery bank is profitable in the long run.
The life of the battery is determined by the charge-discharge cycles and depth of discharge. If you have a larger battery bank, the daily depth of discharge will be shorter and in principle, this will increase the life of the batteries.
You Can Use Solar Energy For Different Purposes
Did you know that you use solar energy for diverse purposes? You have the option to generate electricity or heat, whatever you want.
You can also use solar energy to produce electricity in those areas that do not have access to the energy grid. This means that these areas are in need of a number of resources, including clean water. Without the energy grid, solar energy makes it possible to distill water in areas that have a limited clean water supply.
Solar energy is more than capable of powering satellites in space. You can also integrate the energy into the materials that are needed for buildings. A little while ago, transparent solar energy windows were introduced by some companies as well.

I Cant Afford To Purchase A System Is Leasing Cheaper
Dont be fooled by the low monthly costs of solar leases. Over a twenty year period, you will actually pay much more than if you purchased the solar system. You wont receive the tax credit and its likely that leased system will be made with inferior equipment. Leasing also makes it difficult to sell your house because any new owners must assume your solar lease or you have to buy out the system
Are Solar Panels Worth It For Your Home
Solar panels are almost always a worthwhile investment, especially in places with solid net metering policies and local solar incentives.
Of course, there are certain scenarios in which rooftop solar panels arent a good fit, like if you have nowhere to put the system, you plan to move soon, or your energy costs are already low.

Between the different types of panels, financing, inverters, and other jargon, researching solar energy can feel overwhelming at first. Thats why I recommend starting at a solar quote comparison site like EnergySage, Solar-Estimate, or SolarReviews .
Both EnergySage and Solar-Estimate act as educational resources and comparison shopping tools to help you field bids. Ive been using EnergySage, which is chock-full of articles explaining the technology involved. You can also watch videos, look at their buyers guide, or start getting quotes. Their Solar 101 series of articles will help you understand the basics, and when youre done, scroll through the sites Learn About Solar sidebar to read even more articles thatll give you a feel for the process.
To understand what your home requires, though, youll need to look up how much electricity you use. If your bill tells you the average amount of electricity you use each month, make a note of that, or calculate a quick and dirty average yourself. The more information you have on your usage, the more accurate an estimate you can get from installers.
Your energy usage will determine how many panels youll need on your roof. Too few, and youll still have to pay the electric company for whatever extra power you use. Too many, and youll waste money on panels you dont needthough the electric company will give you credits for any energy you dont use, should you one day need electricity from the grid.
Looking To Reduce Your Dependence On Traditional Power Sources Heres How To Figure Out Whether Solar Is For You
If youve been thinking about adding a solar power system to your home, you arent alone. Some 3 million systems sit atop American roofs, including about 400,000 that were installed each year in 2019 and 2020, according to Becca Jones-Albertus, director of the Solar Energy Technologies Office at the U.S. Energy Department.

Residential Solar Energy Systems: The Basics
The majority of residential solar energy systems are still connected to the grid. This allows you to still have power when the sun is not shining and youve run out of solar energy generated by your own system. Besides always having power available, when youre still connected to the grid, youre eligible for net metering. Net metering is when any unused energy generated by the solar panels installed in your house is fed back into the grid. The utility company then credits you back for the solar energy you are feeding into the grid. Essentially, if your credit is the same or more than what you use from the grid, your bill from the electric company can be $0. In addition to net metering, when you install a residential solar power system, you are also eligible for federal and local tax incentives and rebates that can result in major savings off the top.

Solar Panels Are Not Noisy
If you have seen any solar panels, you will have observed that they do not consist of many parts other than their huge plates. That implies that there is no machinery involved.
We all know how comfortable and annoying it can be when there is a constant noise in your house. Some people who have to use generators for long time periods will understand this dilemma.
With solar panels, you might as well forget that you have something on your roof that is constantly producing energy. Many people prefer solar panels over wind turbines.
Wind turbines also produce clean energy, but there is so much noise around them that it can be hard to hang out in the area. That is why you will notice all the wind turbines are located in farms etc.
How A 100% Green Electricity Plan Is A Great Alternative To Solar Panels
With its perpetually sunny climate, Texas ranks in the top 10 U.S. states in its cumulative solar capacity. As a result, the Texas solar industry has grown rapidly in terms of electricity generation and the number of people it employs. With it, household enthusiasm for solar panels has also increased. However, the two main concerns people have when it comes to solar panel installation are production capacity and costs.
Solar panels in residential settings currently face limitations since most homes have no way of storing extra solar power on sunny days when solar panels create more electricity than the home can use. Thankfully, further technological progress will likely address this storage problem, as it plagues the entire industry.
In regard to costs, regular electricity companies can offer lower rates on traditional electricity plans than those powered by solar energy because of an economic concept called economies to scale. In essence, the costs for each additional unit of output decrease as more output is created. In other words, because more households are connected to the Texas electricity grid than use solar panels, the average cost of electricity is lower for each household than it would be with individual solar panels.

Solar Charge Charge Controller
As the name suggests, the solar charge controller handles or regulates the DC power from the solar panels. As we know, the magnitude of the DC voltage depends solely on the intensity of the sunlight and may be varied continuously.
So the Solar Charge Controller performs a function to control the varying DC input to the Charge Controller. As a result, the battery and the loads are getting a constant DC voltage.
In addition, the solar charge controller protects the batteries from overcharging, which increases the battery life in the long run. Also, it prevents the reverse power flow from the battery to the solar panels.
The modern charge controllers are capable to manage the charging and total control of the inverters. Controllers used in hybrid inverters are smart enough to control the charging, utilization of DC input, selection of grid supply, or DC input.
Depending upon the working techniques used in the solar charge controllers, they are classified as
- PWM solar charge controller.
- MPPT charge controller.
Benefits Of Solar Energy
Is solar a good source of electricity?
The short answer is yes, because the solar energy, while not absent from disadvantages, has several advantages:
1. Receiving electricity from solar energy can help you lower a buildings utility bills, so you can save money by installing a system for the collection of solar energy.
2. The fact that traditional means of receiving electricity impact global warming is a well-known fact, but by using solar energy to produce electricity you may improve the situation by reducing air pollution.
3. Further, solar power does not belong to anyone, as it is with fossil fuels, which means that anyone can use solar energy to produce electricity with no need to buy it from other countries.
This possibility means that countries that do not possess old fashioned means of producing electricity can gain some independence from those that do.
4. The sunlight is a renewable resource, unlike fossil fuel, and it is available for a long time from now while being an excellent source of energy.
These are only four of the most obvious benefits of solar energy, but there are more reasons why solar panels are good.
