1 Harvesting Solar Energy Overview of Systems, options and benefits of Solar Energy Systems By:John Miggins Harvest Solar Energy renewable solutions to everyday needs 1

2 Solar Energy Potential All Energy is Solar Energy, Let s harvest it directly, use it for providing comfort via Energy, Hot Water, Heating, etc. Enough solar energy hits the earth in one hour to power the world for a year! This is a fantastic renewable, clean resource, how can we use it for our advantage. 2

3 Typical Home Energy Use CFL Light bulbs Plug strips- Programmable Thermostat DC and AC Solar Systems Off-grid or Grid-Tie Solar Energy Audit Solar Air Heaters Passive Solar Heating Energy efficient heaters, Insulation-Radiant Barrier Windows Solar Hot Water Systems Kits or Turn-key Tax credits! 30% on Hot water & Solar Electric Systems Ask about our $7500 tax Credit Savings Program Cool Attic- Attic Fans Cool Roof Tight Envelope Geothermal/ energy efficient Cooling Whole house fan Harvest Solar Energy Products and Strategies for Real Energy Savings 3

4 Solar & Wind Hybrid Systems 4

5 Solar System Components Solar Panels Charge Controllersfusing, wiring Batteries Inverters Mounting Wiring, grounding Monitoring 5

6 Solar Panel Considerations Type - mono, poly, amorphous, ribbon, bipv, concentrated, silicon or copper based Function to generate POWER - move electrons Density - wattage per square foot Efficiency - conversion of light to energy Durability - withstand the elements Physical properties, heat tolerance, mounting, wiring, grounding, spacing Appearance, form and function, dual use deployment Manufacturer and availability, warranty, useful life 6

7 Grid tie Solar Systems Easiest type of solar electric system, no batteries or maintenance required Solar Panels, mounting, wiring/fusing, inverters DC to AC, 95% efficient Sense grid, if it goes down your system goes down Cost 7 to per watt, minimum size of 1250 watts for around $12,000 installed Tax Credit of $2000 for homeowners, 30% for business owners- though

8 Solar Hot Water Solar water heating and air heating is the most effective and economical use of solar energy. Drainback Solar Hot water systems provide 85% of your hot water Systems start at $2500 and typically cost $3500 to $4500 installed. Savings of $30 to $75 per month, Last 15 to 20 years. The Sun is an effective source of heat for water for home, pools, hot tubs and process heat $2000 tax credit through 2008 for homeowners, 30% unlimited tax credit for business 8

10 Solar Pool Heating Solar Pool heating extends swimming season by 2 to 3 months black polyethelene panels use sun energy directly to heat pool water can raise temp 10 to 14 degrees 50 to 70% of pool surface area in panels facing south, using pool pump, automatic or manual very effective, cost $3500 to $

11 Solar Air Heating Very effective heating source Uses solar energy directly to heat home black metal box that you blow air through Heat in day, insulate well to preserve it Can be a home made appliance Build into the home walls via tromble wall or thermal windows facing south Use the sun when you need it and keep it out when you don t 11

12 Solar Air Heating 12

13 Solar Water Pumping High efficiency pumps can replace AC pumps which are energy hogs DC is more efficient Pump direct, may need a battery system for 24 hour pumping, ideal for livestock, ponds, aerators, cabins, homes Also solar pool pumps to replace AC pool pumps which are also energy hogs Tax Credits, Grants for rural properties 13

14 Top Ten Energy Smart Products Solar Hot Water for lasting energy savings Energy Efficient Lighting Radiant Barrier- Reduce attic temperature Attic Fans Skylights-Tubular and traditional Solar Air Heaters Plug strips-timers/programmable Thermostat Insulation/Windows Passive Design to optimize the solar contribution Thermal Shades to block unwanted sunlight 14

15 Putting it all together Solar Energy is easy to harvest, directly, indirectly and make environmental, economic and sustainable sense Grid tie is easiest- $7 to $8.00 per watt Battery based systems are also available for back-up or remote applications, gate openers, attic fans, pumping What you spend will insulate you from higher energy bills in the future and make a statement for renewable energy now and in the future Aesthetics, Function, Color, simplicity, we can do it all. Go Solar now and REAP the benefits for 25 years 15
