Buying a solar panel system for your home can be confusing if you are misinformed. Since most panels are a relatively new concept for most Americans, some research is needed. Here we gathered some of the most common questions regarding the process of buying a solar panel system for your home.
How many solar panels will I need?
Since there are many types of homes, there are not a one-size-fits all answer. The number of solar panels you will need for your home depends on several factors such as:
1.Your energy consumption
2.Amount of direct sunlight in your area
3.Position of the solar panels
4.Climate (in cooler weather, more energy will be expended to heating your home)
How can I calculate the number of solar panels I need?
1. Begin by assessing your energy needs. Take a look at your monthly energy bills through the course of the year to estimate your average monthly consumption. Be sure to include bills from every season to account for changes in consumption.
2. Next, evaluate the daily amount of direct sunlight in your area throughout the year by going to the Renewable Resource Data Center website and searching for your area. The more direct sunlight you get, the fewer panels you will need.
3. Look for energy specifications per panel on the vendor's website. Consult the vendor for an estimate of the number of solar panels.
Where can I find out if my state has an incentive program for buying panels?
Go to the Renewable Resource Data Center website for specifics about your state. Many states have some guidelines you must abide to receive a state rebate. Check the specifications carefully. Should I install the panels myself or hire an expert?
If you are trying to cut costs, you might consider installing the panels on your own. However, you should only attempt this if you are adept at wiring electrical cords. If you are not sure you can install the system safely, consulting a professional is always a better option.
Do the panels require some type of maintenance?
If you live in a very dry area, you will need to clean your panels of dust periodically, since dust will reduce the panel's ability to absorb light.
I don't have a lot of money to devote to buying panels at the moment, can I buy just a few and add more panels later? Yes. Investing in one or two panels is a great way of reducing your electricity bills in the long run. You can use the money you save to add more panels in the future.
