Base - Solar panel - Between cover glass and transparent adhesive places luminiferous additions which makes solar emission stronger in air-bubbly cover-up.
Appearance - Form will be as a tile; color can be changed - Can be placed in different types of tiles, but the most effective is as showed on picture, because during whole day panel can collect right solar emission. To change color is able to put active (reactive) colorants out of they can outstay high temperatures, their lifetime is really long and they aren’t very expensive.
Price - Not more than 35$ - For 1 tile which produces ~ 30W of electrical energy. The person who buys the product can easily calculate how many tiles he needs so not to waste more money on useless. The buyer can save some also because he shouldn’t buy usual tile in place of my product (For my home I’ll need ~100 tiles and it will pay for it-self ~ after 1,5 year)
