Новая закаленная стеклянная солнечная панель 6В4Вт 270 * 170 мм Модуль-фотовольтаическое самостоятельное производство электроэнергии.

New stock solar panel, 4mm tempered glass panel, the overall is very heavy, rated voltage 6V, outer box marker is 4W, board size 270mm * 170mm, thickness 4.2, solar panel measured power generation efficiency is very good, at the end of October, Zhejiang, the sun is not very hot at noon. The short circuit of the board is almost 650-700ma under the vertical sunlight at noon. It is estimated that the current is much larger in summer, the measured no-load voltage of the board under the sun is more than 7v.

The nickel strip drawn out behind the solar panel has not been welded. You need to do soldering iron welding by yourself, close to the positive pole inside, close to the negative pole outside, and use epoxy glue or high-strength silica gel to seal and reinforce the nickel strip after weld line, the nickel tape is not fixed well and will easily break.

The tempered glass board is relatively heavy, and the single board weighs 395 grams.
