Don't be scared off from solar energy because you see certain companies shutting their doors. Solar energy is a big part of the country's future. It's not only great for the environment; it also saves you a lot of cash. That's a win-win across the board, and you'll be happy for looking into it now.
When you create your own solar power, you can actually make money off the process. It is possible for you to sell your extra power to an energy company in your area. If you think you would be interested in this, get in touch with your local power company and talk to them about how it would work.
UPDATE: When not in direct sunlight, it can take forever to charge. Be patient if you buy this. 19 bucks last I checked on Amazon: https://amzn.to/2mFFJS4 …
If you cannot afford a full-scale solar energy system, consider investing in a smaller one. Some vendors offer small systems designed to power a water heater or a generator. This small investment should help you save money within the next few years and you can easily expand your solar energy system by powering more appliances with solar panels.
