Many people aspire to being completely off the grid. Simply, this means installing a big bank of batteries, and enough solar panels to manufacture all the electricity you need and then cutting your tie to the grid.
McNae Electrical Solutions supplies very small systems for tiny houses, motorhomes, cabins and small cottages. These start at less than $2,000 for DIY solutions. Fully installed solutions start from under $10,000. For normal sized homes the costs (fully installed) typically start from:
Small house $20-30,000
Medium house $40-50,000
Large house $60-70,000
A generator is also required. This can be integrated into the system with auto-start functionality so that it seamlessly provides power if there has been too much cloud or to boost the power that is available from the batteries for running large loads. You should allow from $6-14,000 for a quality auto-start generator.
Off grid solar is not just great for your house. Many farmers rely on off grid solar to pump water around their farms. McNae Electrical Solutions can provide water pumping solutions for any conceivable need. We can pump water as far and as high as required. Our water pumping systems are designed without batteries, so the water is delivered with smart high efficiency DC pumps that constantly adjust their output according to the sun as it shines during the day. A solar pumping solution completely replaces the need for grid electricity or diesel pumps, thus reducing costs, improving water security, and making farms more sustainable.
The service provided by Martin from McNae Electrical Solutions was excellent and we are very satisfied with our solar power system.
