One of the top things to look at when considering what company to go with is the cost per kilowatt-hour over a 20-year period. This shows how long it will take for you to break even. If this number is 5 or under, then it’s worth looking into because you will be making money right away.
Other things to consider are state rebates and tax breaks. Maryland currently has a 25% federal rebate available for systems purchased through December 31, 2017, that have an expected performance date on or after January 1st, 2018. This means that having your system installed by the end of the year can give you up to $6,000 off via a rebate from Uncle Sam! And if you own your system rather than lease it, Maryland also gives a tax break of 50% of the first $5,000 in income from your solar system!
Lastly, installation costs play a big part. This is basically how much it will cost for your system to be hooked up and running which you want to make sure they’re a reasonable price. You can use Google’s calculator or other energy calculators available online to see if having solar panels is even worth it for you. Other factors need to be considered before buying such as the size of your roof and affordability for both purchase and maintenance.
