Need answers from those who know how to generate solar electricity, from interior of home, into the electric panel so that electric company buys what is not used,and or how to use solar to charge batteries to store energy for non sun hours for heating our home..Prefer Do It Yourselfers that have had success. Thank you very much

Big question.
selling to the grid needs an expensive ‘grid tie’. You could look at a 12v system for lighting, or solar water heating and a large sump, but when it’s cold you don’t get much sun, probably better with wind.
I’d do some googling if you’re serious.
you cannot generate electricity cheaper than you can buy in most cases. They only way a PV system is economical is if the state pays for more than 50% of the cost or the power rate is over $.30 kw-hr or a combination.
If you want the most efficient electric heater, you will need a geothermal electric heat pump. You could not afford solar panels to run a heat pump system as the running amps are HUGE. You would be grid tied and have to have a netting meter. You also could not afford the battery packs required to store the amps intermittently between when the heat pump is off and on.
For a project like this I recommend a licensed contractor unless you have extensive experience. If you tie it to the grid so your meter runs backwards you will need to submit plans to the utility company. This option is usually less expensive than adding a battery storage system.
I have a system installed, it is a 3.75 kw dc system and it currently is meeting about 75% of my energy needs. It cost me about $16 K and I should break even in about 6 years.
Try the DIY kits section of this site below that you can build a device for under 200 that will generate electric and will be safe for the environment.
