The Solar Power System is a basic independent solar power plant designed to generate hot water and electricity for home or industrial use, satisfying basic needs such as lighting, TV, notebook, fridge, ceiling fan, and water pump in rural areas. The Solar Power System can be coupled with local electricity grid or can be installed 100% off grid using a battery power system.
Photovoltaic Solar Power Off Grid Home System
The Photovoltaic Solar Power System Off Grid is designed for rural areas where public grid utility is missing. Excess power generated during the day is used to recharge the battery set that will supply electricity during the night.
Photovoltaic Solar Power Grid Connected Home System
The Photovoltaic Solar Power System Grid Connected or Grid Tied is always connected to the public grid utility through the inverter that convert the direct current DC, generated by the Photovoltaic Panels, into alternating current AC for use in your facility. Excess power generated during the day will be sold back to the utility for a credit to be used in the night when sunlight is not available. It is the right choice if you have a stable and reliable electricity grid but you want to save the energy bill.
Photovoltaic Grid Tied Solar Power System with Battery Back-up
The Photovoltaic Solar Power System with Battery Back-up is the right choice if your national grid isn’t reliable and the event of outages is not uncommon. During the day your home will use power generated from the solar panels, and the excess power will recharge a small battery set that will become a source of emergency backup power during blackouts. During the night you will use power from the grid and only in the event of grid blackouts, our system will switch to off grid mode drawing power stored in your battery to power your home.
Standard Home Photovoltaic Solar Power System
The standard Photovoltaic Solar System is based on 2.500 W output power and includes:
- Photovoltaic Solar Panels (8 modules) to generate electricity.
- Mounting rack to easily install panels on the roof or in the garden.
- Solar charge controller.
- Energy storage lead acid battery set.
- High performance inverter with low status consumption (Efficiency > 90%, Suitable for heavy load, standby level adjustable, High ambient temperature design).
- Low voltage, high voltage, overload and over temperature protection set.
- Inverter output: 110 V / 220 V AC.
- Frequency: 50 / 60 Hz Automatic tracking main frequency.
- LED lighting for low energy consumption on request.
Please note, the standard home design is for 2.500 W power according to following terms: the power output is calculated on areas with daily average peak power sunshine of 5 hour, and the battery set capacity is designed for power storage of 10 hours output in saving energy configuration of your home.
How Photovoltaic Solar Panels Works
A Solar Energy Plant is a great way to power your home with clean, renewable energy and cut the electricity bill. The Photovoltaic System consists of a few photovoltaic modules connected in a series, array. Each module consists of 36 or 72 cells that convert the light into electricity. The photovoltaic system is modular, high flexibility in power ouput, easy transportation, quick installation. The photovoltaic cell is the main component of the panel and converts the light to electricity. During the day, the cell absorbs photons (part of the sunlight particles which contain energy), and an electron (negative part of atom) is knocked loose from a silicon atom, and remains a positive hole. The cell is made by putting an artificial junction layer, p/n layer, that keep separated the freed electron and the positive hole, generating electricity when we create an electric circuit between the front and rear of the layer. Now the freed electrons can return to the positively charged holes by flowing through our external circuit. The electrical power extracted from a cell is proportional to the intensity of the sunlight. The efficiency of solar cells when convert sunlight into electricity is 15% of thermal sun power.
Solar Photovoltaic Panels Specifications

Solar Controller & Inverter
The Inverter is the brain of the solar system and converts DC electricity to AC electricity for your home uses. The inverter is always coupled with a controller that monitors the utility grid and controls the solar system production.
Orientation of Solar Photovoltaic Panels
Here are many considerations to do about the orientation of Solar Panels including site shading, site conditions, different climatic circumstances, installation costs and aesthetics. The rigth orientation will produce the most amount of energy production per year, but many systems can take into consideration for example an existing roof and will be installed in a non pefect orientations, with only a small reduction in total output. The first rule is to never install a solar system that faces in any portion of the 180 degree arc of the compass that faces north, or in the shade of a building or a tree even if the new solar microinverters allow solar panels to operate independently of each other, and if one or two modules end up in the shade of a building, the others will produce electricity.
How to Calculate Home Photovoltaic System
An ordinary appartment uses 2.500 W. During the day 8 solar panels can totally supply energetic consume of an appartment. The battery set will supply the electricity in the night and thanks to the inverter will be transformed from 24V to 110V or 220V for house equipment uses.
During the day:
The 8 solar panels produce 2.500 W. If you use less energy, you can store the excedence in the battery. If you have only conditioner turn on, maybe 1.000 W, solar panels supply air conditioner and you put 1.500 W in the battery. For 10 hours of sun, you can put 15.000 W in the battery.
During the night:
To know how much electricity you consume, add all electrical equipments power (W) and multiply by the hours that are turn on. TV is 200 W for 3 hour per night = 600 W
Radio is 20 W for 2 hour per night = 40 W
Light is 100 W for 4 hour per night = 400 W Conditioner is 1.000 W per 5 hour per night = 5.000 W
Total power for 1 night is 6.040 W The battery must supply minimum 6.040 W during the night, it means teorically 6.040 / 48V = 125 Ah. Because of battery efficiency is 75%, we use a battery size 48V – 150 Ah.
