2KW Off-grid Stand Alone PV Photovoltaic Solar Hot Water Heating Heater MPPT

No More Frost in WinterNo More Overheat in SummerNo More MaintenanceNo More Plumbing Photovoltaic Water Heating with MPPT + Mains Backup Charge Normal 230VAC Element DirectlyBy 8x260W Solar PanelsThis Unit For Water Heating Only Please Note: You can buy cheaperfrom https://www.ebay.com.au/itm/253430180590 What is a PV Water Heater?You know this situation… a hot summer day, not one cloud in the sky, the sun is shining and there is nowhere to hide, your car is blazing hot, so you can´t even keep your hands on the wheel, and while you are having shower in the afternoon, you are thinking: Why do I even pay for heating of water? Why do I consume gas, or electricity, when the sun heats for free? You are not the first ones to think about this. After all, the sun collectors for heating water aren´t new. However, collectors have their disadvantages. They work with the warmth from the solar radiation, so they are not very effective during winter. Moreover, they are quite demanding to install – all those pipes, valves, pumps, and necessity to watch the whole system in winter, so it wouldn´t freeze and in summer as well, so it wouldn´t overheat. Let´s try to think of a different way. What if we used a photovoltaic panel instead of solar collectors? Exactly those that are used in power plants. Their technology is getting better, thanks to boom of solar power stations, their price is getting lower. Moreover, they use light, not warmth, so instead of special transfer liquid and pipeline, they use electric cable. Also, they don´t freeze in winter and don´t overheat in summer, so they are pretty much maintenance-free. Electricity, which they produce, could be used to heat water in boilers. Sounds like a good idea, doesn´t it? But if we connected a photovoltaic panel to a heater, it wouldn´t be very effective – sometimes, it would heat water too much, sometimes not at all. We need some kind of device which could process this energy effectively, i.e., send it to the boiler when we need to heat water, use the rest of it (e.g., to recharge accumulators) but also, when there isn´t enough electricity from the panels, it would be able to use electricity from the electrical network, so we wouldn´t end up without warm water. PV Water Heater is just the right control unit. At the beginning of the whole system there are photovoltaic panels, at the end there is your common electric boiler, and in between there is a PV Water Heater, which controls everything, so you always have enough warm water, which has been heated predominantly, by the Sun. Surplus of energy can be used, e.g., to recharge accumulators, deficits can be covered by electricity from the distribution network. The PV Solar Heater also considers the fact that the sun doesn’t always shine with the same intensity. Therefore, it tracks so-called point of maximum power of the photovoltaic system (this technology is known as MPPT, Maximum Power Point Tracking), which is a way how to process current and voltage from the photovoltaic panels according to the intensity of the sunshine, so the output of panels is at its maximum at all times. Yes, it´s true. No collectors, pipelines, heat exchanger, circulating pumps, special heat transfer liquids and no need of frequent maintenance! Only photovoltaic panel, electrical cable, control unit and an ordinary electric boiler.

Sometimes also, the BSC is characterized using its equivalent efficiency defined as the efficiency of a monofacial cell able to render the same power per unit area as the bifacial cell at the same test conditions. Alternatively, the equivalent efficiency has been defined as the sum of the front and rear side efficiencies weighted by the relative amounts of irradiance on both sides.Another related parameter is the Bifaciality Factor, defined as the ratio of the front and rear efficiencies when illuminated and measured independently.{displaystyle {text{Bifaciality factor }}(%)=left[{frac {eta _{text{front}}}{eta _{text{rear}}}}right]times 100}Also specific to BSCs is the Separation Rate , that intends to measure the Bifacial Illumination Effect predicted by McIntosh et al. in 1997 by which, the electrical output of BSCs operating under bifacial illumination would not necessarily equal the sum of the front-only and rear-only electrical output, i.e. it is not merely a linear combination of the monofacial characteristics:{displaystyle {text{Separation rate }}(%)=left[{frac {X_{text{front+rear}}}{X_{text{front}}+X_{text{rear}}}}right]times 100}Typically X represents one of the cell characteristic parameters such as the short circuit current Jsc, the peak power Pmax or the efficiency η. Furthermore, to characterize BSC operation under simultaneous front and rear irradiation, the irradiance gain, g, defined as:{displaystyle g={frac {G_{f}+G_{r}}{G_{f}}}} so that {displaystyle x={frac {G_{r}}{G_{f}}}=g-1}and a bifacial 1.x Efficiency can be defined as the efficiency obtained under a simultaneous irradiance of a certain amount on the front face and x times this amount on the rear side of the BSC. Then the actual gain of a BSC with respect to a monofacial one can be expressed through the Gain-Efficiency Product, which is the product of the irradiance gain g and the bifacial 1.x Efficiency. references Ohtsuka, H.; Sakamoto, M.; Koyama, M.; Tsutsui, K.; Uematsu, T.; Yazawa, Y.
