How many solar panels will I need for my home? The number of panels you’ll need for your home will depend on several factors. The easiest thing to do is to look at your electricity bill to get your home’s hourly energy usage, multiply that by the peak sunlight hours for your home (3 to 5 hours on average), and divide by 300, which is an average wattage for solar panels (although they can range from 150 to 370). Hourly energy usage x peak sunlight hours / 300 = number of panels. This typically ranges from 17-42 panels. One simple way of answering “How many solar panels do I need” is to let a local solar installer check out your home and give you a quote for system size (including number and wattage of panels), cost, and estimated annual and lifetime savings. Let our Solar Advisors match you with the perfect installer in your area.. Which is the best type of solar panel? There are several types of solar technology, but almost all home solar panels use crystalline silicon (monocrystalline or polycrystalline). The main difference is the purity of the silicon. Monocrystalline silicon is made from a single-crystal, and polycrystalline silicon is made by melting silicon fragments together. In monocrystalline panels, there are fewer impurities, so the electrons are less likely to get blocked before leaving as electricity, thus these panels are “more efficient” or better at turning sunlight into electricity. German produces the highest efficiency monocrystalline solar panels available. The best Solar Panels have efficiency of up to 22.8 percent, making it the best performing panel on the market today. Polycrystalline panel efficiency typically ranges from 15 to 17 percent. You may ask, Why do high-efficiency solar panels matter? More power in less space. A high efficiency rating ensures your solar system will generate more electricity with fewer panels on your roof. Fewer panels with more power are great for smaller roofs as well as maintaining curb appeal on larger roofs. Plus, with fewer high efficient panels, you’ll have room to expand your solar system if you get an electric vehicle or add on to your home. Right now. Using fewer materials per watt is also great for sustaining our planet. In fact, it’s a double benefit, because less energy is required to construct the system, and more solar energy is generated at a faster rate. Do solar panels wear out over time? In short, yes. Your roof isn’t a very hospitable place, so conventional solar cells lose power over time because of corrosion and breakage. To save cost, these solar panels are commonly built with less durable design and materials.

The shade of trees:
If your solar is under performing over time then this will be due to the tree growth. Installers assume that you will keep your trees trimmed, there are also some places there are laws that ensure your right to the access of the sun. You will get these rights once you have done the solar panel installation on your roof, you will also get it also means that you should also have sun access from your neighbors’ trees as well. This factor is often overlooked and has an impact on the system’s performance. Some people call the solar panel installers to maintain the system but sometimes the trees are the culprit.
The inverter needs to be changed every 10 to 15 years, however, make sure that the inverter is on and working so that you get the energy you want. Most inverters have a green light which indicates that all is well so always keep your monitoring on so that you know if the inverter goes out of function as it will affect the performance of the solar panel.
Though some dirt is okay, if the solar panel is extremely dirty or covered in ash then you should definitely clean them. For this purpose, you will need professional services for maintenance so that the panel gets clean up and also achieve a basic check that will ensure you that the system is working optimally. The cleaning procedure is also crucial because if the cleaning is done by the soap that leaves residue then the sunlight will get reflected by the panels instead of absorbing the sunlight.
Buying solar panels for sale will greatly reduce your electricity bills and provide you a large number of ongoing savings. Wiser people are turning towards solar panels because they are fully aware of the benefits it provides. Solar panels for sale are now being offered for lesser prices because of the government subsidies and advancement in technology. Solar panels also help the environment by decreasing the carbon emissions. Despite so many benefits and advantages, selecting a solar panel is not always easy. There are a number of factors that you should consider while buying solar panels for sale. This post will help you to understand some of these:
How do they work?
Before you purchase the solar panel for sale, you must know how it works. It generates electricity from solar energy and can also work on cloudy days because they do not need direct sunlight or heat energy instead of the light energy from the sun. The solar panels have an inverter which transforms the direct current into alternating current which is used in the homes. The electricity is then used to fulfil your needs if you generate more than you consume then the electricity goes back to the grid and when you consume more than you generate then the light is provided from the grid.
This factor is important because the solar panels generate the most electricity when facing on the south-facing roofs. If you have east or west facing roofs then also solar panels are a viable option because they will still generate electricity. The roof’s angle also plays a part in the generation of electricity because solar panels work effectively at 30 to 35 degrees. The installer should measure the roof before installation so that you have an idea that how well it will perform at your house.
The maintenance of solar panels is very less, if the dirt or leaves accumulate over the panels then they can easily be cleaned. Also, the solar panels come with a warranty of at least 25 years and the inverter has a warranty of 5 to 10 years. The inverter needs to be changed after 10 to 15 years because it works continuously, therefore, has more chances to get damaged. The installer must check your solar panels every 4 to 7 years, don’t forget to ask the maintenance requirements of the solar panels.
Good quality solar panels and installation are not inexpensive and usually, you receive what you pay for. So if you have purchased the solar panel for less price than average then you might receive a poor quality equipment and installation. Also, some service might not be included which also lowers the price however, you must gather different quotes and details before having an agreement. You may also receive some package deals but not every package has the same quality services. We, LA Solar Systems Inc provides the best solar panels for sale and for best prices.
