SunPower - is one of the undisputed world leaders among manufacturers of solar modules. The company produces solar modules, which occupy:

1st place in the world in terms of efficiency - 22.7% (Maxeon X22-370W module)
1st place in the world for reliability - 10 times more reliable (0.005% return)
1st place in the world for the lowest degradation - no more than 0.25% per year (Maxeon)
1st place in the world in terms of environmental friendliness (SVTC rating, Cradle to Cradle)
1st place in the world with a warranty - 25 years for both product and productivity up to 92%

Between 2007 and 2016, SunPower spent more money on research and development than any other crystal module maker.
There are two types of models on the market: Performance and Maxeon

Advantages of Maxeon panels:

The world's highest efficiency of photovoltaic modules - up to 22.8%
High reliability: 10 times more reliable (0.005% returns). The modules are resistant to fluctuations in temperature, wind, humidity, hail and other damage.
World's smallest degradation: actual no more than 0.2% per year, guaranteed no more than 0.25% per year
One of the best temperature coefficients: - 0.29% ºC for MAXEON3 (X-series)
Increased generation: on average 7-10% more from each watt than in conventional modules, as well as in the morning, evening, heat, cloudy weather, winter and other real conditions
When shaded and soiled, the generation is 20-40% higher than in conventional panels. Each element has diode protection
25-year product warranty, regardless of defect
25-year power guarantee: 92%
Estimated operating time: more than 40 years

Solar power plants can be made in three versions: Grid-connected solar power, hybrid station or autonomous system.

Grid-connected solar power plant (On-Grid)

The system consists of two components - an array of photovoltaic modules and a network inverter.

Grid-connected SES is designed to reduce electricity consumption from the grid and to sell surplus electricity to the grid of the local energy company at a «green tariff»

Mains SES does not provide for the possibility of accumulating electricity and is not equipped with a rechargeable battery (battery), the battery is a central network.

The mains inverter synchronizes with the mains and converts direct current from solar cells to alternating current. In such a system, it is important to have a bidirectional meter that will take into account the amount of electricity consumed and delivered separately. If more electricity was produced than consumed during the month, the state buys surpluses at the price of the «green tariff».

Hybrid solar power plant (Hybrid)

The most complex and versatile type of photovoltaic system, as it has the advantages of network and stand-alone systems.

The hybrid photovoltaic system works both as a grid and stand-alone, saving electricity during the day and not running out of electricity if the general grid is disconnected.

The hybrid system allows to sell surplus generated electricity to the network of the local energy company at a «green tariff»

Autonomous solar power plant (Off-Grid)

A photovoltaic system that acts as a primary or secondary source of electricity.

Electricity generated by a stand-alone system that is not supplied to the public grid, but only feeds facilities connected directly to that system.

The main task is to ensure uninterrupted power supply to the consumer.
