LOCAL GOVERNMENT IMPLEMENTATION CITY OF ELBERTON 2 Solar Sites City Hall (10 kw) and Customer Service Center (15 kw) Summer - 2011
Elberton Solar Energy Projects Funded through Electric Cities of Georgia ARRA grant from GEFA 2/3 of costs paid by grant 1/3 by City 2 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 system 5 kw seems to be the smallest installation Do not over size (costs will outweigh benefit) Use your power bill to find kw Demand, that is your building s electric peak Ask your power company for help

Solar Implementation Check with your power company on interconnection standards and requirements Power company will charge an interconnection fee and require a contract Can install without interconnecting to power grid Inverter requires A/C power to operate Will 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 offgrid. 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?

What is the Market Today in North Georgia? 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
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.
Projects in Hall County KOS wire solar farm 528 Schüco MFE 185 MS 06 Solar modules linked into 48 strings by 11 modules to 12 SunnyBoy 8000W 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
