Solar energy products

When we mention the term "using solar energy", we immediately think of solar panels for generating electricity. Well, someone will remember that there are also solar convectors for heating water (more on them below). And for what kind of country affairs can you still use the free energy of the sun on a clear day?

1. Solar grill

Thanks to such a device, in sunny weather, you can cook food, bake any dishes. Consists of a reflector and a flask where the tray with food is placed. Sold by Chinese manufacturers on alibaba and aliexpress. Cost: $ 50-95.

For hiking, picnics in nature, where there is no firewood (on lakes in the steppe, for example) - an interesting option. Yes, and in the country - to surprise guests and loved ones. Of the minuses - the flask is difficult to wash from the inside. You can do it yourself if you have a glass flask, a piece of tin and a mirror film.

This grill works even in winter at -10 gr. I looked special reviews on YouTube. Yes, not as efficiently and quickly as in summer, but you can fry sausages in winter, but in clear weather.

I don't know if this picture is photoshop or true, but some Africans have acquired stationary solar grills. Focusing sunlight with a large lens also has an effect. I remember, as a child, on a sunny summer day with a lens 5 cm in diameter, I burned wood. And here the lens diameter is a meter!

There are other options for solar grills:

These are models from Western manufacturers and it is not always possible to purchase them with delivery to Russia.

In addition to the topic: on aliexpress for hiking there is such a device for lighting a fire without matches and lighters:

2. Solar drying cabinet for harvesting herbs, berries, mushrooms

It's simple. The inclined part with glass absorbs sunlight, heats up and hot air enters the cabinet, where herbs or berries are laid out on a grid, on pallets. And they dry out quickly enough. there is a movement of hot air. Electric dryers work on this principle.

3. Solar convector for heating swimming pools and getting hot water in the house

The water in the pool heats up in half a day and in the second half of daylight hours you can already use it comfortably even for children. They say that such solar convectors under glass work even in cloudy weather.

More powerful water solar convectors are also suitable for heating water in the house:

In summer they are very effective, especially in the southern regions of the country. But the cost of factory models is still high. And not everyone is ready to do homemade products. Although there are examples on YouTube.

The use of solar energy is not limited to these examples. For example, using an old parabolic plate covered with a mirror film, you can melt metals (cast lead fishing tackle).
