Planning For a Solar Panel
The first step in purchasing a solar panel is to determine whether your home gets enough sunlight. If your home is in a sunny area, it will produce more electricity during the day. If it’s in a cloudy area, you’ll probably need a tracking mount. Some private dealers sell solar panels. To obtain a subsidy or loan, contact the renewable energy development authority in your state. The REDA will give you a subsidy or loan amount.
The second step
is calculating how much money you would save if you were using solar energy. To determine how much money you would save with a solar panel, go to your electric utility company and calculate the average of your last few bills. You should try to find at least six months’ worth of bills to compare with. Make sure you account for seasonal temperature fluctuations and other fluctuations. Assuming you will be using your solar panels 100 percent of the time, you should spend approximately $125 per month or $1500 per year.
Once you have estimated your expected savings
you can begin the planning process. To calculate the amount of money you will save with a solar panel, you will need to determine your monthly electricity costs. To do this, you should log into your electric utility account. Then, make sure to calculate the average cost of your last several bills. You should take at least six months’ worth of bills to make sure you’re taking into account seasonal temperature changes. To calculate the cost of a solar panel, assume you will use 100% of the panels. That should give you an idea of approximately $125 per month and about $1500 per year.
When planning for a solar panel
it’s important to consider your electricity costs and your expected savings. It’s important to note that solar panels have a “useful life” period. Once installed, your solar panels can produce as much energy as you need for the next decade. Depending on the type of solar panel you choose, you may see a noticeable decrease in energy output after about 25 years. Fortunately, many manufacturers offer warranties that guarantee 90 percent of the production of the panels for the first 10 years and then reduce the output over the next twenty to thirty years.
A solar panel’s efficiency
is determined by individual solar cells. A single solar cell is composed of layers of silicon, phosphorus, and boron. A silicon wafer acts as a semiconductor. The electrons in this sandwich are knocked out by photons from the sun. The result is a directional current. For a residential solar panel to be effective, you should expect to generate approximately 750 watts per day.
