A few of the final parts and pieces are left to complete the install of a 30 KW system on North Avenue in Grand Junction.

Take a gander at the latest picture:

30 KW Installed Solar Electric System

I was driving by one of our installation sites today, and there were some guys installing solar panels on the roof of the building.  I pulled in across the street and took a quick picture, so you can see a job in process.

Description of location:
1: Latitude: 37.653 N Longitude: 106.660 W Elevation: 7750’
2: Declination: 9.8 deg E
3: Lowest Temperature -34deg F: Highest ambient Temperature 78 deg F
4: Total Electricity used/Year: 44,863 KHW Total Cost/Year $ 4,640.17
5: Panel Pitch: 35 Deg
6: Hours of Solar Radiation: 6.33 Hours /day fixed for summer

Picture of sunlight hours for House site: The site has 98% of sunlight hours. Sunlight 6.33Hrs / Available 6.20 Hrs

Calculate amount of solar needed to meet Electrical needs:

1: Average solar per Month: 44,863 KHW/12 =3,738.6 KWH/Mth
2. Average solar per day 3,738.6Kwh/30 = 124.612 KWH
3: Amount solar per hour: 124.612 / KWH/6.20hrs*1000watts/1KWH= 20,099 Watts/Hr
4. Inverter efficiency: (20,099 watts/hr)/.96 = 20,936 Watts/Hr
5: # of Sharp 235W panels: 20,936W/235W= 89.089 or 90 panels
6. # Inverters: 3 Sunny Boy 7000US (240V) Inverters
7.  System Size 21.15 KW
8. Actual Size:  15.51 kW

This home installation of a solar PV grid tied system is 7.128 KW in size.

Redlands One Before

The installation covers two section of roof, for a total of 33 Sharp panels operating at 216 watts each.

Redlands One After

A Sunny Boy Inverter 7000W was used to connect to the grid.

Redlands One Electrical

Nth Degree Solar Energy installed a 5.824 KW system on the owner’s home, as part of some reconstruction improvements.

725 Hill - Before Solar PV Install

The system consists of 28 Sharp Modules of 208 Watts each:
