There are no chemicals, which are emitted when the energy is being produced. There are no spills which must be cleaned up.

They require no existing infrastructure, which must be purchase for the public good. No wars or negotiations have to be made with foreign countries over resources. The sun is available at your home or business site to be used for clean energy.

Saving money with solar energy systems

Solar energy systems create energy which can be used by homes or businesses. Greentech can design and install a residential or commercial solar energy system for you which can reduce or eliminate your energy bill. Our solar water heating systems and solar water pumping systems will pay for themselves in less than five years. If incentives are available in your area, our electricity generating solar panel installations have short payback periods as well. The best thing about solar energy systems is that once the system is paid for, the electricity that they generate is free. If you install one of these systems, you will not have to worry about the cost of electricity going up in the future.
