1 Most Cost Effective Solar Energy Solutions Topics Our company mission US Power Grid Threats EMP effects on Solar be less energy dependent # solar panels & batteries needed 10 Ways to shop for solar systems by Tom Brennan Engineering Manager

2 Sol-Ark makes EMP/Solar Flare Hardened Solar Systems Our systems survive >100KV/m EMP testing >140 times. Military requires 50KV/m We are a Veteran owned engineering company with the mission of helping families be less dependent on our vulnerable Power Grid in an affordable way. Educational info on website & YouTube channel.

6 Sol-Ark.com 1500W Inverter, 260W Solar, 1 Batt How Many of You Have Solar? 1250W Inverter, 60W Solar, 1 Batt

7 Sol-Ark.com How much power do you need? = 2 men 250 Watt Panel 12V 110Ah 250W x 5 full sun hours = 1.25KWh 12V x 110Ah = 1.3KWh + consuming 2000 calories / person

8 Power Needs Sol-Ark.com

9 Power Needs Sol-Ark.com

10 Sol-Ark.com Power Needs 2 6 Very Low cost solutions cannot even run a Fridge. 9 36

11 Types of Solar Panels Poly Mono Thin Film + Least Expensive per Watt + Pretty - Cost ~15% more than Poly + Fits any flat surface - Cost ~33% more than Poly - Low power density - Finding a flat sturdy surface - Many brands don t last Sol-Ark.com

12 Sol-Ark.com Online Energy Calculator Calculates Panels & Batteries for large systems: Calculates Panels & Batteries for smaller uses:

13 How Many Batteries? Few Batteries = rapid solar charging and deep night discharging = much shorter battery lifespan Sol-Ark.com

14 6 x Panels (1.5KW solar) + 4 x Batteries Powers: Sol-Ark.com

15 15 x Panels (3.5KW solar) + 12 x Batteries Powers: Heating / Cooling requires a lot of power Sol-Ark.com

16 Sol-Ark.com 10 Ways to Shop for Solar Systems

17 Sol-Ark.com 1) 30% Federal Credit + 25% Rural REAP + State Incentives 30% to 55% solar cost is paid Fed & State Incentives going away. Utah = $1600 Why are you waiting?

18 Sol-Ark.com 2) Look for Battery Based Solar Grid Tied Inverter Meter Inverter

19 Sol-Ark.com 2) Look for Battery Based Solar Grid Tied Inverter Meter Inverter

20 Sol-Ark.com 2) Look for Battery Based Solar 99% of installed Systems are Grid Tied AND don t work if the Power Grid fails or Off Grid.

21 Sol-Ark.com 3) Look for Reduced Electric Bills, not DIY backup Get Grid Interactive, Hybrid, or Multi-Mode System. Reduced energy bills are the biggest way solar systems pay for themselves. Most DIY backup systems only use panels when the Power Grid fails.

22 Sol-Ark.com 4) Don t Deep Cycle Batteries & they last 10+ years Get Grid Interactive, Hybrid, Multi-Mode System: keep batteries charged. Most DIY systems only switch to Grid when batteries are fully depleted & cycle batteries deep every night = 2-3 years life.

23 Good systems = 10+ years Most DIY systems = 2 years Sol-Ark.com

24 5) Good Solar Panels last 50+ Years Sol-Ark.com

25 Sol-Ark.com Solar Panels Handle baseball size hail. Self cleaning with rain.

26 Sol-Ark.com 6) Expandability: add panels & batteries later Get Solar Wattage: 250W x 2 (500W) to 250W x 12 (3KW) Don t confuse Solar Watts with Inverter Watts! 2 Why you need lots of Panels 3000W of solar x 5 full sun hours = 15KWh / 24hrs = 625W/hr AVG

27 Sol-Ark.com 7) AGM best for Grid Backup, Li-On for Off Grid Tips Wet Lead: corrode terminals, gas, maintenance kwh Cost Justification AGM Wet Lead Tesla Li-On Other Li-On Gel Cell: charge slow AGM/Wet/Gel: Go by weight more than Ah. The more lead, longer they last. # of Batteries Volts per Unit Total Voltage Amp Hours kw of Storage kwh kwh kwh kwh Li-On: Prefer 10-45C Usable Storage % % % % kw Cost $2,000 $1,600 $10,500 $7,000 Cycle Life Span 1200 cycles 2000 cycles 4500 cycles 5000 cycles Total Energy Throughput 3,800 kwh 6,620 kwh 29,700 kwh 25,480 kwh Cost Per kwh $0.52 kwh $0.24 kwh $0.35 kwh $0.27 kwh

28 FYI, Modified Sine will not run freezers, gas furnace, clocks, and some electronics. Get Pure Sine. Sol-Ark.com 8) Off Grid Inverter Idle Power Bigger Inverter is not better. 12 Panels = 625W/hr AVG 240W x 24hr 100W x 24hr 25W x 24hr

29 Sol-Ark.com 9) Install Solar Yourself and save 35-50% Solar Installers charge ~$1.5/Solar Watt to install Off Grid solar 12 Panel 3KW $4500 labor You can install newer All-in-One solar systems like the Sol-Ark (or get an electrician for $500).
