Invest in energy efficiency if you are out of roof space. You can spend money on anything from better appliances to insulation to reduce consumption.

Or simply rely on your grid tie to make up the surplus. If you only meet 80% of your energy needs…. Well that is fine. You reduced your power bill by 80%. Stop worrying about 100% solutions.

As for expensive prices right now, ever hear about the chip shortage? China fucked up hard between covid lockdowns and the complete collapse of their power grid this year. The answer is patience, grasshopper. We’ll get back into a PV equipment price falling price cycle quickly enough. EVERYTHING is overpriced and expensive right now. All the forecasts are for the chip market to shift from famine to feast (glut) within 6-18 months. It is a 3+ year cycle for industry to ramp up and we are over half way there.

You’ll also probably see all sorts of rebate programs come and go. The governments of the world are offering all sorts of subsidies. Milk one.

You can also put a PV system on your garage, shed or even in the yard. We have a 3kW system on the old bus that we use as our RV and I am wiring a new breakout plug in my shop so that when the bus is plugged into shore power it will heat and cool my shop.
