Solar thermal has three categories of heating, 1 the sun direct energy warming a mass, usually brink or masonry, 2 sun direct energy warming air using a collector to warm the air as it passes through the collector, and 3 sun direct energy warms a fluid, just like air but the medium is now a fluid used to transmit the heat to a storage tank.

Is customer owned hydro turbine, that produces energy all year, or during colder seasons. Using a small stream located near remote cabins, small farms, small businesses and homes. Usually consist of high upfront cost, BUT, if maintained will provide a long service life, with a great source of energy and a great return of value. Depending on your energy demands you will need a minimum of 5 gallons per-minute at 80 feet of head or 15 gallons per minute at 15 feet of head. Micro hydro is a great combination with photovoltaic solar to make a hybrid energy source, because streams tend to flow more water in fall, winter and spring when the sun irradiance is shortened or it is cloudy.

Is a customer owned wind turbine, that produces energy for remote cabins, small farms, small businesses, homes, even sail boats and more. Micro wind is a great combination with Photovoltaic solar to make a hybrid energy source, because wind blows even when the sun is not shining or on cloudy days.

Is just a solar panel like you see on roofs and in fields.

A self consumption renewable energy system consist of most of the same components as a standalone renewable energy system, except when the SOC% (state of charge) of the batteries drops to a set percentage, all AC load transfer to the utility grid, this allows you to use the energy you produced from your renewable energy source allowing for a smaller renewable energy system, but not limiting energy consumption. Let’s say you have friends or family visiting and need a few more kilowatts, not a problem. This example is a brief introduction to a self consumption system; your AC loads have consumed 20%* percent of your energy storage and no sun, wind or hydro is available or minimal, so, your energy storage is at 80 SOC%* and transfers the AC Loads to the grid, leave you with 30%* energy storage in-case the utility grid is unavailable at that time. This will give you the freedom and security knowing your critical loads will have power 24/7, and worst case scenario we can add a generator as a redundancy if grid is down longer than expected with no sun, wind or hydro available or minimal, this rarely happens but also depends on size of your renewable energy system. (* most energy storage chemistry only allows 50% of the battery to discharge from the battery bank)

A stand-alone renewable energy system consists of energy storage batteries, inverter (convert CD to AC), a charge controller allows us to properly charge batteries from a renewable energy source such as Photovoltaic solar modules, Micro Wind, Micro Hydro.
