Yes.
Rewiring is possible, but is best done when renovating the house. Depending on the power of the photovoltaic system you install, you can dedicate a circuit to the photovoltaic system in your home. For experimental domestic photovoltaic power generation, the battery investment is about 10,000 yuan per kilowatt, including an inverter (to convert direct current to alternating current), brackets, cables and batteries at lithium.

It is recommended to use lithium batteries, which have a longer lifespan than lead-acid batteries. Depending on the specific electrical appliances, a battery pack of around 36V 100Ah is estimated to cost more than 5,000 batteries. There may also be costs for building renovation or otherwise. Probably close to 20,000 yuan per kilowatt. If the battery is higher than the lightning protection net, you can make a lightning rod and connect it to the lightning protection net. You can consult your trustee when installing photovoltaic cells, as long as it doesn't affect your property, everything is fine.
Can the solar water heater installed in the new house be used for bathing in winter? Winter in Shandong is very cold, who can use it to warm up?
As long as you reserve the interface, there is nowill have no problem. The solar water heater is installed on the roof. There are only two water pipes and a few cables connected to the house. interfaces for water pipes and cables in advance. From the kitchen Or if the bathroom is to be open, the protruding water pipes should be installed together, so that there is no need to drill holes in the future. The socket must be reserved, preferably a 16A socket.
Solar water heaters are designed to standards to reach around 40 degrees on sunny days in winter, so you can take a shower without cold water. Of course, there are also some brands designed to reach around 35 degrees on a sunny day. The two kids upstairs said it was 70 degrees. This is because the solar water heater they bought was large and the hot water could not be used. When the weather was nice the next day, the temperatureThe base temperature of the water was high, so the final temperature was high. pupil. If it was a new one, a whole can of cold water is not enough. You can ask Huangming, Tsinghua Sunshine and other top brands about it. They don't dare say it reaches 70 degrees. In winter, solar water heaters can reach bath temperature, so it's easier to buy a larger one. It can be used in Northeast China, and of course there is no problem in Shandong. Although solar water heaters are frost-free and can also produce hot water, the section of pipe from the solar water tank to the interior is frost-proof. During installation, insulation must be carried out, as well as an electric heating tape (a kind of heating tape). electric heating tape) should be installed inside the insulating layer (the heating device plays a role in protectingprotection of the pipes against frost), so that you are not afraid of frost.
