SOLAR PROJECTS

All solar power systems work on the same basic principles. Solar panels first convert solar energy into DC power which can be stored in a battery or converted by a solar inverter into AC power which can be used to run home appliances. Depending on the type of system excess solar energy can also be fed into the electricity grid to provide credits and further reduce electricity costs.

ON GRID SOLAR PROJECTS

On-Grid Systems are solar pv systems that only generate power when the utility power grid is available.  They must connect to the grid to function.  They can send excess power generated back to the grid when you are overproducing so you credit it for later use. These are are simplest systems and the most cost effective to install.  These systems will pay for themselves by offsetting utility bills in 3-8 yrs. These do not provide power during a grid outage. They are simple enough that you can install it yourself in a weekend with a friend.  They are cost effective enough to pay for themselves and put money in your pocket long term.  If you want to reduce your electric bill and your carbon footprint this is a good choice.

OFF GRID SOLAR PROJECTS

These systems allow you to store your solar power in batteries for use when the power grid goes down or if you are not on the grid.  Hybrid systems provide power to offset the grid power whenever the sun is shining and will even send excess power to the grid for credit for later use. Provides power for your critical loads when the power grid is down. Cannot be expected to provide power for all your loads since the cost and volume of batteries would be prohibitive. Off-Grid systems require a lot more specialized equipment to function that is more costly and more complex to install.  Specifically they require a central/string inverter, a charge controller as well as a batteries.

EPC SOLAR PROJECTS

The Wolt Techniques engineering, procurement, and construction (EPC) team provides bankable, innovative, and reliable solar energy solutions to customers around the world. Offering “turnkey” working systems due to the set structures ESA has in place, we are able to provide a complete spectrum of services for projects from viability studies to commissioning.
