Sizing a system for your home is easy.  Simply provide your last 12-24 months of kWh usage, along with the address the solar is to be placed, and we will provide a detailed online quote with a visual layout.  We will give you the maximum allowable solar for your site to get you as close to 100% as possible, along with different mounting options if your roof is not optimal or large enough.  We will also provide a second option to help lower your usage with options to add later.

THE INVERTER WITH THE MOST OPTIONS: SMA-America inverters are the most diverse grid tie inverters on the market.  SMA's Sunny Boy series is the only grid tie inverter with a secure power supply (SPS), an outlet that will give you access to your solar energy during an outage. 

SMA America is also the only string inverter that gives you the ability to add optimizers to one or all modules, giving owners and installers more choices and simplicity in design.

SMA-America's Power + Solution (MLPE) is a flexible option that works to mitigate shade losses and/or provide individual module monitoring. The optimizers are only necessary if partial shade is a problem, and other lower cost MLPE’s are available simply for monitoring and rapid shutdown requirements coming in late 2019.  If only one module has partial shade, one MLPE(Module Level Power Electronics/DC Optimizer or TS4-O) can be fitted to that one shaded module.  Other brands of inverters with MLPE's, such as SolarEdge with DC Optimizer technology or Enphase's micro inverter systems, require a MLPE device for every module in order for the entire system to operate.

Our goal is simplicity!

When designing your system we want to minimize the possibility for failures by avoiding extra unnecessary devices that are usually in hard to reach locations, like under each module on top of the roof, for example.

Some will argue that string inverters are not as efficient as micro inverters based on claims of efficiency and also with the “Christmas lights” analogy.

The max efficiency is as follows per system. SMA without TS4 optimizers added = 97.5%; Enphase = 97.5%; Solaredge = 98%

It is true that if one panel is shaded or fails in a string of modules (usually 9-13 per string) the entire string will stop producing while it is shaded. While this is true, many times shading is not an issue, and if it is a problem, SMA’s TS4-O shade optimizer can be placed on that single shaded module.

Modules have a very low failure rate. Inverters, however, are known to fail. When comparing a 36 module string inverter system with a micro inverter system, you have 36 times more chance for an inverter failing.

String inverters are usually located in a cooler environment where the inversion process will be more efficient, and they will be much more accessible.

Want individual panel monitoring instead of per string inverter?  SMA’s TS4-S can provide this and rapid shutdown at a lower cost than a traditional DC optimizer.  They can be added at any time.


Tax rebates and other incentives are available.  The 30% federal investment tax incentive (ITC) for business' and residential, through a tax break that is spread through 10 years if not used in the first, will pay for 30% percent of the total cost of the system.  This incentive will start to taper off after 2019.  

Depreciation with the new tax bill, solar electric systems can be depreciated 100% in the first year, or by 85% if the 30% ITC is used in conjunction during tax time.

USDA's REAP Program, or Renewable Energy for America Program, offers a 25% grant, and loan guarantees, to qualifying rural business's.  For example, a poultry farm could have over 55% of there system paid for, and thats not including the 85% depreciation.
