Are Solar Panels Efficient
Some solar panels convert 22 percent of their available energy into electrical power. This is an actually amazing number if you consider the fact that we are paying a lot of our electricity bills every month. The solar panels are made of solar cells. A cell is a small disk of a semiconductor like silicon. They are attached by wire to a circuit. As light strikes the semiconductor, light is converted into electricity that flows through the circuit. As soon as the light is removed, the solar cell stops producing power.
A solar pool heating system uses the suns radiant energy to heat your water. The water is directed to the collectors, rising from the bottom to the top. As it gradually rises, its heated by the natural energy and then returned to your pool. This cycle continues until your pool water reaches the desired temperature. You can enjoy an added 10-13° to your water without any extra costs or air pollution!
How Much Can You Save With Solar Thermal Panels
Annual savings resulting from the installation of solar thermal panels vary, according to the fuel type used in your existing system. A saving of £95 per year is possible if your system is gas, and £150 if its oil, according to the EST.
There is currently no payback system for generating your own heat with solar panels, as the government closed the Renewable Heat Incentive to domestic applicants in March 2022. Therefore it takes at least 30 years for solar panels to pay for themselves on savings alone.
The Costs Involved When Installing A Solar Power System
Aside from how many panels you need, the price of a solar system will vary significantly depending on the quality of the components:
Solar panels are designed to last decades, however, all solar panels drop off in output over time as they age. Better quality solar panels on average last longer, they provide more output and they are more reliable. They also cost more money.
We recommend going with a reliable brand such as LG Solar or Trina Solar, and we would be happy to provide pricing for different panels to help you make an informed decision.
With a 5kW system, you can expect to pay an additional $1,000 to $2,000 for top-of-the-range 360W high-efficiency panels compared with a mid-range panel. You can save some money upfront by choosing a cheap Chinese panel, however, we strongly advise against it due to a reduction in quality, performance and reliability: A Warning About Cheap Solar Systems
The Inverter. Solar panels output DC power. This needs to be converted to AC so it is compatible with your home. All solar systems come with an inverter that converts DC to AC, and because it is the working part of the system it is the component most likely to break.
For this reason, Solaray only offers the top handful of brands from companies like Enphase, SMA and Delta. A cheap inverter from China may cost $500 compared to $2000 for a European Made equivalent.

Solar Heating And Cooling System Cons
- Higher purchase price and installation costs than conventional systems
- Inconsistent heating and cooling
- Dependent on home location and orientation
- Installers are not available everywhere
- Manufacturing processes still contribute to pollution
Although it has dropped significantly in the past few years, the upfront cost of solar technology is still higher than conventional tech. But the return on investment happens rather fast. Solar space heating and cooling systems can pay for themselves in as little as three to six years. When combined with domestic hot water and electricity production, the benefits only increase. While solar may not be the right choice for every consumer, it does offer a viable alternative to fossil fuels.

At What Point Do Solar Panels Pay For Themselves
So, when exactly do you get your money back after shelling out for a residential solar panel system? The answer to this question is also dependent upon factors such as how much electricity you normally use, and how effective your system is. Naturally, if your family uses a lot of electricity, then your solar panel system will start paying for itself much faster than if you use very little.
That being said, in most cases, solar panel systems typically pay for themselves in 7-20 years. If you were able to knock your costs way down with incentives and you normally use a lot of electricity, you can expect to be ahead of the game well before the decade is out. If you paid a little more money up front and your energy use is average or less than average, then you might have to hang in there a while longer before you recuperate your costs.
That being said, once your system is installed, all youll notice is the fact that youre paying little or nothing at all on your electric bill every month. And once the system pays for itself, youll be enjoying extra savings in your pocket every month for free. For some, it is possible to save $20,000 or more over the life of the solar power system.

Hardware Costs Versus Soft Costs
When you think about a solar system, you might think that itâs the hardware that makes up most of the expense: the racking, wiring, inverters, and of course the solar panels themselves.
In fact, hardware accounts for only 36% of the cost of a home solar system. The rest is taken up by soft costs, which are other expenses that the solar installer must bear. These include everything from installation labor and permitting, to customer acquistion , to general overhead .
Soft costs have been dropping, but not as dramatically as hardware costs, as shown in the graphs below:
Youâll also notice that soft costs become a smaller percentage of system costs as the system size increases. This is especially true as you go from residential to utility scale projects, but large residential systems generally also have a lower price-per-watt than small systems. This is because many costs, such as permitting and customer acquistion, are fixed and donât vary much with the system size.

How Much Does A Solar Panel Really Cost
People are usually skeptic about the solar panel cost but through years of innovation and product development the cost of solar panels has decreased significantly. Solar panels weigh up to 20KG and can be easily mounted on to various roof types, the solar panel installation cost varies from the equipment needed to set the right inclination of the solar panels and installment of rackings for mounting. The location of the site also affects the price due to shipping and manpower.
Another factor you have to consider is that the cost of solar panels vary from suppliers and the EPC. Which is mainly differentiated through Quality and efficiency. Most low cost solar panels dont offer the same warranty as the leading brands.
The recommended Solar PV system size is around 2kWh and costs about Php200,000. It enables you to save up to 3,000php a month for the next 25 years . The Solar panels costs after installation are minimal allowing you to acquire the return of investment within 6 years and save ++850,000php over the years. Some suppliers for Home solar panels cost half the price but dont guarantee your ROI and the Lifespan of the system.

How Do I Choose The Right Home Solar System
There are a few things you need to consider when choosing the right solar system for your home:
The first thing you need to ask yourself is whether you want a grid-tied, off-grid solar system or a hybrid, grid-tied and backup solar system.
The second thing you need to ask yourself is how much money youre willing to spend on an off-grid solar system.
The third thing you need to ask yourself is how much sunlight your roof gets. All of these factors will help determine which type of solar system is best for your needs.
Once youve answered those questions, its time to do some research on different solar companies and compare quotes. Be sure to ask each company about the federal tax credit and any state or city credits or incentives they may offer. You can also finance a solar panel installation if your budget doesnt allow you to buy them upfront.

What Are The Advantages Of Solar Panels
There are many advantages that solar panels offer. Advantages include reducing a monthly electricity bill, low maintenance costs, and the benefits to the environment that solar can provide as a renewable energy source. These are all reasons that can persuade someone to install solar panels on their home. Here is a closer look at these advantages in more detail5:
- Reduction and/or elimination of electricity bill: Depending on how much of your energy needs can be met by the newly installed solar system, you could dramatically reduce or eliminate your monthly electricity bill. If you happen to generate more electricity than you use, you may be able to sell the surplus energy back to the power company in some regions.
- Low maintenance costs: Maintenance on solar panels is highly minimal. Cleaning the solar panels a few times a year and replacing the inverter every 5 to 10 years are the only maintenance requirements. Additionally, many solar panel manufacturers offer 20 to 25-year warranties.
- Environmental benefits: Solar panels can provide all the energy you need for your home without using power generated from burning fossil fuels like coal, oil, and natural gas. Utilizing solar energy can reduce your carbon footprint and help slow the harmful effects of climate change and global warming.

The Solar Tax Credit: Solars Best Incentive
The best incentive for going solar in the country is the federal solar tax credit, or the investment tax credit . This incentive allows you to deduct 26 percent of the cost of installing solar panels from your federal taxes, and theres no cap on its value. For example, a 10 kW system priced at the national average comes out to $27,600. However, with the ITC, youd be able to deduct 26 percent of that cost, or $7,176, from your taxes. This essentially reduces the cost of your system to the $20,424 price tag we highlighted at the beginning of this article.

Investigating Whether Solar Panels Actually Save You Money On Your Energy Bills
Solar panels can be costly to install, leaving some homeowners wondering, do solar panels save money? Over the long term or maybe even short term, solar panels should pay for themself and save you money. In addition, they are environmentally friendly. When calculating the cost and savings that solar panels offer, you should consider tax rebates and other incentives. So, how much money do solar panels save? Keep reading to find out.
How Many Solar Panels Do I Need
Your energy needs determine how many panels you need, which affects the overall price of your solar system installation. To eliminate your electric bill entirely, you must generate 100% of the electricity your home needs. Most homeowners need between 25 and 35 panels to achieve complete energy independence.
Average households need867 kWh/monthin electrical power
A solar panel typically produces about one kilowatt-hour per day, so if your daily kWh usage is 30, you would need 30 solar panels to generate all of your energy needs. If you need to generate extra energy to heat a pool or run the air conditioning for most of the year, this adds to your energy costs.
To estimate the amount of energy youll need, you need to know your average kilowatt-hours . This number should be on your utility bill as kWh used. To get your monthly average, look at bills for the past year, add up the stated kWh used and divide by 12.
Next, divide your monthly kWh average by 30 to calculate your daily average. For instance, if your average monthly kWh is 900, then your average daily kWh is 30.
For a more accurate calculation, try to factor in times when there is not as much solar power available, like when its cloudy or in the evening. There are two main ways to account for this:
These additional calculations can be difficult, but they are necessary if you want the optimum solar power system for your home.

Whats Average And Whats Going To Make The Price Fluctuate
As with anything, once the newness of something wears off, the price starts to decrease as well. Thats one of the key reasons behind the 12% decrease in solar system prices from 2015 to 2016 alone. In addition, more manufacturers across the globe are producing solar panels, also contributing to the price drop. Its not so much of the novel thing that it was just five years ago to have solar panels installed at your home anymore. What does this mean for you, the homeowner? Nothing but good! Prices are falling, incentives are great, and youre able to lower your electric bill. But, if youve been quoted at a different price than the averages listed above, theres good reason. These numbers are just averages and can vary because of a number of factors. Types of solar financial incentives vary state-by-state. And the size of the system you get and need for your home will also vary the price. Adding one more watt to your system can raise the average price of the system from $12,500 to $15,000. And doubling the size of your system from 5 kW to 10 kW will increase your costs to about $25,000 to have the system installed.
