2.Our solar panels systems can keep work in bad conditions like wet weather,snow..
3.Our soalr panels system has 25years warranty to keep the power output and quality.
11.Solar power is the best choice for you
With a business or residential grid connect system, your house or property is still connected to the mains power supply, so battery storage is not required. A grid connect installation ensures you have the electricity you need, whenever you need it - automatically and regardless of conditions.
Other applications for solar energy include hot water systems and solar powered pumping. Learn more about each type above and don't hesitate to contact us - we have a professional team of friendly experts who can help you to choose the suitable soalr panles to meet you needs!
Solar Power Basics
1,What is PV?
PV is short for photovoltaics (photo=light, voltaics=electricity). PV is a semiconductor-based technology used to convert light energy into direct current (DC) electricity, using no moving parts, consuming no conventional fuels, and creating no pollution.
2,How long has PV been around?
The photovoltaic effect was first recognized by Edmund Bacquerel, in France, in 1839. Scientists made solar cells of selenium in the 1880s. And, modern PV technologies were developed at Bell Labs and RCA Labs in the mid 1950s.
3,What is the difference between solar power and solar hot water?
Solar panels take light from the sun and make electricity. Solar hot water systems take heat from the sun and heat water. It is easy to remember:
Heat from the sun heats the water, Light from the sun turns on the lights.
4, How does electricity get stored for use after sun goes down?
Two options are an off-grid/RAPS (Remote Access Power System), or a grid connect system. Grid connect systems direct excess electricity produced during the day back into the local electricity grid. This turns your electricity meter backwards in the process. You then receive credit for any power that you put back into the grid. At night time, you automatically use electricity straight from the grid. RAPS systems store energy produced during the day in deep cycle batteries for use as required.
5,What happens with grid connect systems during a blackout?
The grid connect inverter will automatically shut itself off within a few milliseconds of a blackout, to avoid the potential of a dangerous "brown-out" in your home and to prevent back feeding into the grid. Therefore even though you have a solar system during a blackout you will not have power available. A generator is the best option for back-up. If you want to keep on having electricity available during a blackout then you would need to have back up batteries installed as well, which will dramatically add to the cost of the system. This backup system does not at any stage feed into the grid.
6, Can you retro-fit battery backup into a grid connect system?
Yes, battery backup systems require additional components similar to an Off grid system, such as, solar regulator, batteries, and off grid inverter and the right grid connect inverter that is compatible with the off grid inverter.There are only a few manufactures that offer this system e.g. SMA and Selectronic - this process does cost a lot more. This system does not feed into the grid when switched over to battery backup (batteries do not feed into the grid at any stage).
7, Will I need to re-roof my house?
In most situations, the PV panels can be easily removed and reinstalled, with minimal, if any, changes to your roof.
8, Is my building suitable for a solar system?
Several aspects will need to be evaluated to determine if your home is a good solar site, such as orientation, space available, shadows on the space available and your current electricity usage. The best site will be one with adequate unshaded northerly facing roofing. Variations on that will cut into the productivity of the system.
9, Can solar panels work in the shade?
The output of any panel will be reduced or cut off if shaded. However, some solar panels do work better than others in the shade. If a single cell is heavily shaded, that cell is cut off.
10, What about the energy it takes to produce a solar power system?
Although solar electricity is pollution-free, PV systems require a certain amount of energy, which must be'reimbursed' before they can be considered as renewable and clean. This is known as "embodied energy". An assessment from the International Energy Agency concluded in mid 2006 that roof-top solar PV systems recover their energy content (from manufacturing and recycling) within 1.6 to 1.8 years in Australia.
Once they have reimbursed their initial energy input, roof-top PV systems can avoid the emission of 40 tonnes of CO2, depending on their location and on the local electricity mix available. Roof-top PV systems in Australia during their 30 year lifespan are expected to produce around 17 times the amount of energy needed for manufacture, installation and dismantling.
11,How much of a reduction in carbon dioxide emissions will I achieve?
Using a comparison to a car, the average vehicle in Australia travels 20 000 km per annum, which is equivalentto 3.3 tons of carbon dioxide discharge annually. A 2kw grid connected systemwill prevent 3.3 tons of carbon dioxide being generated through coal fired powergeneration - so it's the equivalent of taking a car off the road each year.
