The Mr. Solar® 45 Watt Solar Panel kit is our response to the typical consumer-grade kits popular among DIY'ers, hobbyists, and emergency and survival preppers. Our single, high-efficiency, poly-crystalline solar panel will withstand high wind pressure, hail and snow load. Our high-efficiency panel carries a 5 year marterial and workmanship warranty, 90% performance up to 10 years, and 80% performance up to 25 years. Our high-quality Morningstar SG-4 charge controller is warrantied for 5 years and will ensure that your batteries are not under- or over-charged.
Our 45 Watt Solar Panel Kit Includes:
VLS 50 Watt Solar Multi-Crystalline PV Module Panel - PDF SPEC SHEET - At just under 4 sq. ft., this multi-crystalline panel is much smaller compared to the Harbor Freight 45 Watt Kit's 9 sq. ft. amorphous thin cell panel area, giving you lots of elbow room in areas where space is at a premium. Our solar panel includes a 2-year warranty on materials and workmanship compared to the Harbor Freight 45 watt solar kit which has only a 90-day warranty. Our solar panel is an industrial grade PV module that is high-impact resistant, including from hail damage, and made from durable materials including an aluminum frame. Compaints about the quality of the consumer-grade Harbor Freight solar kit, which uses amorphous panels, being "shabby" or "flimsy" are common.
Morningstar SG-4 Solar Charge Controller - PDF SPEC SHEET - A 4.5-amp controller is sufficient to replace the frequently discarded voltage regulator in the other solar kit. Our regulator, which is an actual industrial-grade battery charge controller, includes a 5-year Warranty. The the other consumer-grade solar kits have only a 90-day warranty and their voltage regulator is often quickly replaced by people who purchase that other kit! So, why even bother with it?
Complete Wiring Kit including the module-to-controller and the controller-to-battery wiring. While the consumer-grade wires that come with the HF kit are kinda nice, the Mr. Solar™ 45 watt solar panel kit requires only one panel instead of three and the wiring we include in our kit is industrial-grade and is correctly rated for this type of power system. Our kit includes a 20' length of MC4 output cable, which will be cut in half to create two 10' lengths to connect the solar panel's MC4 cables to the charge controller, and 36 inches of #10-1 controller-to-battery cable.
Expand This Kit to a Deluxe 45 Watt Solar Power System:
In order for your solar panel kit to be even more useful, you'll need one or more batteries. If you want to power AC appliances like a TV or can opener or a fan, you'll also want to grab an inverter. These two items, together with the kit, comprise a complete 45 Watt Solar Power System.
MK/Deka 8AU1H AGM 12V (Optional) - $89.00. This is a 32Ah battery that is sufficient for a small scale system. Includes a 1-year warrany. This is an industrial-grade solar power system battery designed specifically for this type of application. Always be careful when it comes to batteries and battery charging and choose the right battery!
Zamp Solar 300 Watt Pure Sine-wave Inverter (Optional) - $158.00. The Harbor Freight kit page suggests that a 300 watt inverter is required to run AC loads with their kit, which is not included. So, why not invest in a quality pure sine-wave inverter that provides continuous power and 300 watts of surge protection, with a cleaner electrical signal that sensitive electronics use. Supplied with terminal battery clamps and terminal rings. Take our word for it, don't go cheap at Walmart for your inverter. You'll just end up wishing you hadn't gone for the cheapest product.
