Off-Grid Solar PV Electric

SOLAR ELECTRIC MODULES convert sunlight directly into electricity with no moving parts, no maintenance, no fuel, and no pollution.

Wind Generated Electric Power

Great Solar Works! wind systems are designed for the amount of power needed, quantity of water to be pumped, well depth, and strength of wind resource.

Hydro Generated Electric Power

Great Solar Works! hydro systems are designed for the amount of power needed, seasonal or perennial flow of available water, and grid-tied or off-grid application.
Backup Generators
A secondary power source that automatically kicks in to provide electrical power when the power goes out. 
Solar Hot Water Systems
Solar water heating systems use south-facing solar collectors to capture solar energy to heat water.

Solar Direct Injection Radiant Floor Heating Systems
Solar Direct injection is a simple closed-loop solar radiant floor design that is solar heated. 

Radiant Floor Heat & Snow Melt Systems
Radiant Floor or "warm in-floor" heating uses solar collectors in conjunction with floor materials with thermal mass such as cement, stone, and adobe.

Water Pumping & Filtration Systems
Water pumping systems for livestock or irrigation. We also offer filtration systems to remove any natural or unnatural constituent such as nitrates, viruses, and bacteria.

System Refurbishing
If your system is not performing to meet your needs, please call us to discuss your situation. We service and revitalize or refurbish under-performing systems designed or installed by others.

After our complex and aging hybrid solar/heating system had been having reliability issues for several years, our long-time heating contractor suggested we work with Dana with Great Solar Works. Dana completely redesigned our system and in the process installed a simplified interface, a new controller, and replaced our solar panels, among many upgrades.   Since then, we’ve had no problems and have realized a higher contribution from solar to reducing our overall energy costs.
