residetial solar ambassador

 

Project Overview
Location Novato, CA
System Size 4 kW
Surface Area 281 sq. ft.
Product Renesola 250 watt
Production 5,777 Wh/year
# of Solar Panels 16

The Selchau family took energy conservation measures before installing a solar PV system, including purchasing an Electric Vehicle (EV). Enjoying clean driving and lower fuel expenses, the Selchau family was still concerned about high energy prices, global warming and achieving energy independence. Solar power for their home was an easy decision.

After speaking to several solar integrators, the Selchau family chose SolarCraft, for its professional service, longevity and knowledge in the industry. After they flipped the switch to solar, they realized immediate savings with a 92% reduction in their monthly electrical bill. Now they can charge their EV any time and with skyrocketing energy prices, not having a fuel or electric bill is a big plus.

Roof mounted, the solar panels help protect the roof as well as help insulate the home. The system consists of 16 solar panels, each controlled by an Enphase micro-inverter. In this configuration, each panel is linked to a micro-inverter to maximize energy production and reduce the impact from shading. Overall system efficiency is increased by 10 – 12%.

Project Overview
Location Sonoma County, CA
System Size 5.9 kW
Surface Area 476 sq. ft.
Product Mitsubishi 185 watt
Production 8,569 kWh/year
# of Solar Panels 32

After continually paying electric bills that exceeded $300, Michael and Robyn Muscardini — of the award-winning Sonoma Valley winery “Muscardini Cellars” fame — knew they needed a more efficient way of meeting their electric needs. To save money and reduce energy consumption, they installed a solar energy system with SolarCraft. Seamless, low-profile solar panels are saving the Muscardini family over 75% on their electric bills every month — while reducing their carbon footprint. They financed their system through the Sonoma County Energy Independence Program (SCEIP) with $0 down and no out-of-pocket cost. You can imagine their excitement when they received their first electric bill of $76 after going solar.

solar savings chartBenefits

  • Will save Muscardini family over $3,000 in electric bills annually
  • $0 Down and no out-of-pocket cost with Sonoma County Energy Independence Program (SCEIP)
  • Project was completed quickly, with no roof penetrations
  • Installed adjacent to existing thermal panels for maximum solar production
  • Panels provide additional roof insulation
  • Will reduce CO2 emissions by 5 tons annually, equivalent to eliminating over 12,000 miles of driving

Novato Solar Energy Case Study, Williams Family

Solar Power Reduces Electric Bill over 75% for the Williams Family

Project Overview
Location Novato, CA
System Size 10.1 kW
Surface Area 535 sq. ft.
Product SunPower 225 watt
Production 15,130 kWh/year
# of Solar Panels 45

As energy prices continued to climb, the Williams’ family electric bill reached $540. To save money and consumption, solar power was the solution for their energy needs. By utilizing SunPower high-efficiency modules, SolarCraft was able to design a system for maximum output for the space constraints of the rooftop.

The Williams’ system can produce an average of 1,260 kilowatt hours of electricity per month — approximately 75% of their average monthly electrical usage. Excess production, called “net metering,” flows back into the grid, for which they receive energy credits. In their first month of generating clean solar electricity, the Williams family reduced their bill to $133. Solar energy proved to be a sound way to take control of their rising electricity bills and minimize their impact on our environment.

solar savings chartBenefits

  • Saves the Williams family over $4,900 in electric bills annually
  • Increases property value without increase to property tax assessment
  • Low-profile, attractive design integrates with existing rooftop
  • Will reduce CO2 emissions by 263 tons annually, equivalent to taking 3 cars off the road for 25 years

For this stunning Novato residence, design was a key factor. In order to maintain the high aesthetics of the property, and also reach the energy goals and optimal performance, SolarCraft designed a system featuring low-profile Sharp panels with Enphase micro-inverters. A typical system features strings of panels connected to one inverter. Enphase microinverters optimize each panel’s performance greatly reducing impacts of shade and generating about 7% more power than conventional inverters. Overall system efficiency is increased by 10–12%.

The Kerns received their first electric bill after going solar and it showed a 65% saving! The Kern’s solar system will provide free energy from the sun for many years while insulating them from future rate increases.
