Why to Install Solar Water Heating First

Solar water heating and solar photovoltaic (panels or PV) are both important technologies to reduce your consumption of emissions producing fossil fuels. But solar water heating is more efficient and less costly than solar panels, which makes it advantageous to install before PV. And if you are heating your water with electricity you can install solar water heating and offset 15-30% of your electricity consumption and then install a smaller and less expensive solar PV system.
