It has become more popular to see on TV or Ads about solar companies or the government promising free solar panels. This makes it important to assess whether the solar panels are really for free or there is a cost attached to it. A home solar system can cost from $11,000 for a 5kW energy system to $ 22,000 for a 10kW energy system. The size of the solar system you choose will majorly depend on your power requirements or the kind of projects you’re planning to venture into. Hence, the cost for installing solar panels on the roof might be an expensive process for some people. The good news are; it is possible to get some free solar panels but you’ve to abide by the contractual terms and regulations that come with it.
