Small household solar power generation system is utilizing solar battery panel to generate electricity,to provide power electricity for domestic appliance.It is clean and permanent energy resource.It was consist of solar cell module range, solar power controller and storage battery. The power inverter is indispensable if need output alternating current 220V or 110V. This system can be applicable for outdoor,big house,middle dwelling and small residence or those domiciles which are difficult to get power electricity. Its system configuration have superior monocrystalline silicon or polycrystalline silicon solar battery panel, have special storage battery without maintenance, photovoltaic off-grid power inverter and computer controller which have the function of over-charge and over discharge protection.It can be designed to become intelligent switch of urban electricity / photovoltaic solar power generation system (PV system). Its maintenance is simple,lifespan is more than 20 years, many kinds of charging mode to complement, both of solar power and urban electricity can charge for the system.
Small household solar power generation system can be classified as off-grid solar power generation system and grid-connected solar power generation system:
1). Off-grid solar power generation system is mainly consists of solar cell module range,controller and storage battery, it still need allocate AC inverter if it provide power electricity for AC load. The storage battery which is charged by solar battery panel can provide power electricity for household load under non-solar lighting or overcast and rainy weather.
2). Grid-connected solar power generation system is that the alternating current which is according with the requirement of urban electric grid and converted by direct-current which is produced by solar cell module range via off-connected inverter directly connects into public electric grid. Usually,grid-connected solar power generation system possess centralized large scale grid-connected generator station which is state¡¯s station. Its main characteristic is to transform all of power electricity which is generated by this system to electric grid, all of these power electricity are arranged by electric grid to provide for users. But this generator station is relative difficult to develop because of huge investment,long circle time to establish and large scale area covering. For distributed small grid-connected solar power generation system,especially for building integrated photovoltaic,it is main style of grid-connected power generator because of small investment,fast establishing, small scale area covering and great government¡¯s support,etc.
Solar battery panel is the core of small household solar power generation system,its function is to generate power electricity which is inverted to be alternating current, then this alternating current would store inside storage battery.Solar battery panel is one of important parts in this system,its transformation rate and lifespan are important factors to decide if the solar battery remain use value.
About the materials of solar cell module range are as below:
1). Battery chip: It is installed by high efficiency (above 16.5%) monocrystalline silicon solar chip, to guarantee sufficient electric power of solar battery panel.
2). Glass: To adopt low iron tempered suede glass, its thickness is 3.2mm, its light transmittance is more than 91% under the circumstance of reaction ranging (320 - 1100nm) of light spectrum of solar battery. It have high reflectivity when the light spectrum exceeds 1200nm.This glass can stand solar ultraviolet radiation without decreasing the light transmittance.
3). EVA: To adopt superior EVA film layer which have UV agent protection,oxidant protection and hardener protection and 0.78mm thickness as sealant and bridging agent between glass and TPT of solar battery.
. Edging: To adopt aluminum alloy which have high intensity and anti impact force as edging. It is also one of high value part of small household solar power generation system.Its function is to convert solar radiation power to be power electricity, or transform into storage battery to store, or push load to work.
You should consider below questions when wanting to install small household solar power generation system:
1). Where do you want to install small household solar power generation system ? How about for the solar radiation daily ?
2). How about for the load power of system ?
3). How much for the output voltage of system, is it DC or AC ?
4). How long hours is working for the system daily ?
5). How many days for the system need continue to provide power electricity when encountering non-solar lighting or overcast and rainy days ?
6). How about the load, purely resistive,capacitive character or inductive,how much large for the starting current ?
7). How many system do you have request ?
Small household solar power generation system have a fast developing in these years,more and more inhabitant find that it is very convenient for them to get power electricity,especially for those area where is difficult to get electricity from electric grid and remote area.Solar power generation can save electric cost and very easy to maintain,this system is increasingly popular in market.
