4 Tips to Select the Best Solar Panels for Your Home
Installing a solar energy system is one of the smartest investments for homeowners. Solar panels are an element of the solar energy system. However, not all solar panels in Bakersfield CA are created equal. Here, we have provided 4 tips to select the best solar panels for your home. But before that, you need to know the important statistics for right comparison.
Important Solar Panel Statistics
Every solar panel has operating temperature coefficients, standard measurements for output, and efficiency. You need to compare solar panels on these aspects to select the best for your home.
1. Nameplate Rating
The nameplate rating of solar panel refers to its maximum power generating capacity. It is measured in the amount of DC (direct current). The solar panels in Bakersfield CA are rated between 200 and 400 which depend on the quality and size of each panel. The nameplate rating is not the final word in power generation as factors like atmospheric conditions; sun exposure, tree cover, temperature, and angle of the roof also matter. According to solar panel experts, panels can vary 5% above or below their nameplate rating. You need to go for higher nameplate rating when selecting solar panels for your home.
2. Efficiency Rating
The efficiency rating of the solar panel tells you how efficiently they convert sun energy into electricity. The efficiency rating of solar panels is given in kilowatt-hours (kWh). If you look at the solar panels available in Bakersfield CA, most will have an efficiency rating between 14% and 20%. As per the experts, don’t get disheartened by low-efficiency ratings. In any photovoltaic system, 80% of energy produced is lost in form of dissipated heat. So even 20% efficiency rating is good in terms of solar panels.
3. Solar Panel Quality
Solar panels are expensive and hence durability is an important factor. You need to look at the quality indicators while selecting solar panels. For example, you need to look for solar panels that meet IEC 61215 standards which is a reliability standard established by the International Electrotechnical Commission. The panels are generally categorized into three groups- economy, standard, and premium. The premium category solar panels are the most expensive and also of the highest quality standard.
4. Warranties and Assurances
Solar panels are a long-term investment. Manufacturer warranties and assurances work to protect your investment. Solar panels are installed outside your home where they have to face different climatic conditions. They degrade over time and their efficiency is affected. Manufacturer warranties ensure the power production of solar panels does not fall below a certain threshold over twenty-five years. Besides, manufacturers also provide material warranty in case a panel fails.
Selecting best solar panels for your home is not rocket science. Pay attention to the factors above and you will get panels that offer good value for your money.
