LOCAL GOVERNMENT IMPLEMENTATIONCITY OF ELBERTON
2 Solar SitesCity Hall (10 kW) andCustomer Service Center (15 kW)Summer - 2011
Elberton Solar Energy Projects
Funded through Electric Cities of Georgia – ARRA grant from GEFA2/3 of costs paid by grant1/3 by City2 Projects – one 10 kW for City Hall and one 15 kW for Customer Service Center
Elberton Solar Energy Projects
Determine the size requirement of your system5 kW seems to be the smallest installationDo not over size (costs will outweigh benefit)Use your power bill to find kW Demand, that is your building’s electric peakAsk your power company for help

Elberton City HallEnergy Generated
Hourly meter readings may not be available from your power provider.
The typical building peaks in the late afternoon when all HVAC is running together.
With solar, the peak is now normally in the morning.

Solar Implementation
Check with your power company on interconnection standards and requirementsPower company will charge an interconnection fee and require a contractCan install without interconnecting to power gridInverter requires A/C power to operateWill not work in a power outage

Overview of Solar Energy
Solar is:• Any conversion of the Sun’s light or radiant energy to usable electric or heat energy– Conversion of the Sun’s light energy to electrical energy by means of a photovoltaic (PV) solar cell (several create a panel) which can be on or off‐grid.
– Conversion of the Sun’s radiant energy to heat energy by means of a crystalize coated or dark coated (i.e. black paint, piping, screening) panel
What is the Market Today in North Georgia?
• Residential – Incentives from government (running out)– Housing market is still declining (Not many investing)– GA Power and EMCs pay at or above retail (PV)– Thermal is best for large families (4 or more in the house)
– Thermal is probably best payback at 4‐7 years– Over flow to pools– Aesthetics improvements on cells (looks similar to sky lights)
– Absorption/Adsorption Air Conditioning coming?

• Commercial– PV and thermal combined
• Reduce electrical costs• Reduce gas/fuel oil costs for H/W heaters and boilers• Reduce emissions• Possible government incentives?
What is the Market Today in North Georgia?
• Industrial– PV and thermal combined (larger systems)
• Reduce electrical costs• Reduce gas/fuel oil costs for boilers• Absorption Chillers• Reduce emissions• Possible government incentives?
What is the Market Today in North Georgia?
• Agricultural– PV Solar
• Remote wells• Pumping long distances (irrigation with booster pumps)• Hydroponics• Electrical power generation with large PV array Solar Farm
– Thermal• Hydroponics• Green houses• Barnes• Fish farms• Hot water production without boilers(storage)
What is the Market Today in North Georgia?
• Municipalities– Signage (i.e. caution signs, school zone signs, etc.)– Municipal Pools– PV and thermal for buildings– Parking lot security cameras
• Recreational– Parks and RV power
What is the Market Today in North Georgia?
Projects in Hall County
• GEFA Grant for Lanier Technical College– 52 KWp of PV across 3 campuses– 30 panels of thermal across 4 campus– 6 KWp of PV for training across 2 campuses– 6 thermal panels for training across 3 campuses
• Will benefit the community at large by providing visible leadership for renewable energy technologies and training while simultaneously saving the state of Georgia more than $2 million over 30 years.
• KOS wire solar farm– 528 Schüco MFE 185 MS 06 Solar modules linked into 48 strings by 11 modules to 12 SunnyBoy8000W Inverters
– Total come out to be 97.68 kW DC STC Rated Solar Photovoltaic System
– The project will take place approximately in the middle of October and will finish early November
– the return on investment will be paid back to the company in a short year
