c) economies of scale.
Typical turn-key grid-tie installations currently cost approximately $3.00-5.00 per watt DC, before rebates, incentives and credits which will cut the installed costs significantly - up to 100%! Residential PV systems typically are 2000W - 11,000W in DC power rating. Commercial photovoltaic systems range anywhere from 2000W to utility-scale megawatt Solar farms. Again, the Federal government allows a 30% tax credit for eligible solar systems. Some states have an RPS, Renewable Portfolio Standard (Virginia has an RPS Goal). An RPS will generally be a catalyst for a REC (reneable energy credit) market. RECs can ba extremely valuable! If you are in a region with an RPS, call today! For these reasons, solar has become affordable for many residential customers and a very good financial decision for most businesses.
Because every house is different and every person's needs are different, we believe in designing each system for our customer's specific needs. You will not see any "kits" on our web site! We will work with you to design a photovoltaic system that meets your needs for the lowest possible cost. Below are several of our trusted brands:
SMA inverters - SMA is the largest manufacturer of solar inverters in the world. Their inverters are reliable, attractive, efficient, and tough.
SolarWorld - the largest manufacturer of solar modules in the US. These modules are arguably the best in the industry.
Sharp Solar - largest distributor of solar modules in the US. We have installed tons of these and they always perform well.
UniRac mounting solutions - the industry standard for traditional mounting. SolarMount is very strong, flexible, and works for virtually all installations.
MageSolar - these modules are efficient, very strong, have the best warranty in the industry, and the highest power tolerances. We like them.
Others inverter and charge controller brands we have installed:
PVP
Selectria
Fronius
Xantrex
Morningstar
GE
Other solar module manufacturers we have installed:
Kyocera
Evergreen
BP
PowerUp
UniSolar (thin film)
Kaneka
Mitsubishi
Ninghbo
If you have a preference in solar modules, mounting, or inverters, ask us about it. Chances are we have experience with them! We will work with you to design the system you want for your home or business.
How much savings can I expect from my PV system? Here is a good formula for determining the output of your solar array:
DC watts x 80% overall efficiency factor (inverter, wire losses, module mismatch, deviations from STC, etc.) = AC output.
AC output x insolation (expect 4.00 - 4.6 hours per day annual average) = Watt-hours generated per day. (Wh / 1000 = kWh.)
For example, you can expect a 5250W DC PV system to produce this much power:
5250W x 4.50 hrs / 1000 = 23.63 kWh DC per day
24.93 kWh DC x 80% = 18.90 kWh AC per day
X 365 days per year = 6903 kWh AC per year
/ 12 = 575 kWh AC per month. You can determine your savings by simply mulitplying your kWh x $/kWh.
In fact, our systems routinely perform 5-10% better than teh industry standard!
Check your electric bill to see how much of your bill we can offset.
Renewable Energy Solutions, Inc. continues to be a leader in customer service and we pride ourselves in our full one-year warranty, individual personal attention, and responsiveness. With our solar roots extending back nearly 30 years and an impeccable reputation for service and quality construction that withstands all that Virginia's weather has to offer, we are the ideal company to turn to for all your solar needs.
