UTILITY INTERFACE SYSTEMS

We now quote a price per watt for fully installed Utility Interface Systems.

Our prices are based on the actual watts (expected performance) that your system will produce based on the CEC/PTC rating of the Solar Panels and includes the efficiency rating of the Inverter. Many companies quote a price per watt using the maximum DC watts of the panels under Standard Test Conditions (STC) without the inverter derate. The difference (about 20%) is very important as shown in the table below.

STC System Size
using max DC Watts		 STC Advance Price
using max DC Watts		 PTC System Size
Actual Performance		 PTC Advance Price
Actual Performance
1.2kW - 3.6kW $7.82 per Watt 1kW - 3kW System $9.50 per Watt
3.6kW - 6.1kW $7.41 per Watt 3kW - 5kW System $9.00 per Watt
6.1kW - 12.15kW $7.00 per Watt 5kW - 10kW System $8.50 per Watt
12.15kW - 24.3kW $6.64 per Watt 10kW - 20kW System $8.00 per Watt

Actual system performance may be affected by orientation, tilt, shading and other factors.
Larger Systems are quoted individually. Call or E-mail us us for more details.

Quotes are valid for Lake, Sonoma, Mendocino and many other California Counties. We will do a free site survey to verify that the system you need can be installed at your location and that your site has no outstanding issues that might change the price. Our Solmetric test and measurement analysis will show you, at a simple glance, your monthly and yearly sun exposure including time of day and percent of total sun available at the site. We will also verify solar panel placement, proper mounting, and connection to your main electric service panel.

We can also design the system specifically to meet your needs. We will file for your rebate and permits. We will do all the legwork and paperwork for you.

HOW TO SIZE YOUR UTILITY INTERFACE SYSTEM

Get your utility bills from last year. Add up the yearly kWh used and divide by 365 to get your average daily kWh usage based on your history. An average residence uses about 7000kWh per year, about 19kWh per day. To determine the System Size divide the daily usage by 5 (the average hours per day of sun in this area over a year). This gives the expected production your System needs to eliminate your historic usage. This number is the basis (wattage)for your system's price per watt quote.

For example if you had daily usage of 26kWh, our basis for the system would be 26kWh/5hr = 5.2kW or 5200 Watts. So our price would be 5200 X $8.50 or $44,200.00, before rebates, tax credit and depreciation. And it includes all labor and materials required to install your complete grid tie system. Plus a full 10 year warranty.

UTILITY INTERFACE SYSTEM INSTALLATION:

We are licensed solar and electrical contractors (C-10 and C-46 #620243) and do all aspects of the installation with our highly trained crews. We do not sub out any part of the installation to outside contractors. We have our own fleet of trucks and we are the largest stocking distributor in Northern California.

1. All systems quoted are based on CEC Rated Wattage for PV Panels.

2. All systems quoted include at least 2 Solar Panel High Voltage Disconnects. (Outdoor, 30 Amp at 600vdc). Most municipalities now require disconnects on the roof (Fire Department) and at the Inverters (Service Disconnect).
3. All systems include the required Utility Disconnect.
4. All systems quoted include SMA Inverters with display.
5. Mounting specifications quoted are fully engineered for 50 lbs per square foot and 125 mph wind. Engineering specifications available upon request. Any special equipment needed for installing the rail mounting system on your roof will be added to our quote after a site inspection. Ground Mounts are also available.

Other Models and sizes available. Call for quote.

UTILITY INTERFACE REBATES:

To calculate the CEC Power Rating, multiply the Solar Panel PTC Rating by the number of panels. Multiply this result by the Inverter Efficiency. This gives you the CEC System Power Rating. Multiply this number by 5 (average sun hours) to get the CEC System Daily Power Rating.
To calculate the maximum rebate for systems under 50kW use the CSI Calculator which gives the Expected Performance Based Buydown (EPBB) amount. It reduces the incentive for geographical and/or design shortfalls. For New Residential constuction go to the NSHP Solar Calculator to determine your incentive. In either case the actual production must be field verified and the incentive adjusted.
For systems larger than 50kW the rebate is paid monthly by the CPUC according to how much power you actually produce. That Performance Based Incentive (PBI) is $0.22 per kWh for Commercial Systems, $0.34 per kWh for Residential. It includes the power you use as well as the power you send to the grid but requires purchasing a Performance Meter and paying for a Monitoring and Recording Service (PMRS)for five years. The PBI is paid monthly for five years at the starting rate. For more information go to our Solar Incentives page.
