Solar Still is one of the best and most economical ways to distill water using the sun’s solar energy. The simplicity of the solar still is that produces clean water for drinking, cooking, and other such domestic purposes by using the sun’s solar radiation to evaporate and condensate dirty or salty water onto an inclined glass plate without the need for filters or electricity
How much electricity does a wind turbine generate is one of the main questions asked by homeowners looking to buy a wind turbine generator. While wind turbine generators are environmentally friendly generators that generate electrical energy using wind power, The type of turbine generator, its blade design and efficiency are all factors which determine its annual power generating performance. Location, wind speed, rotor diameter and variable speed designs for small and mid-size wind turbines all affect its power output. Accurate data of wind speeds and direction throughout a yearly cycle will help in understanding the operating characteristics of a wind turbine allowing for a better purchasing choice
Fossil fuels are non-renewable sources of energy. These non-renewable sources of coal, gas, oil and peat took thousands of years to form and cannot be replaced quickly during the persons lifespan. Fossil fuels exist in the earth in fixed amounts so need to be conserved before they become fully depleted. Mineral deposits of granite, slate, sand and gravel are also non-renewable sources being excavated and consumed for construction at an alarming rate. The use and burning of fossil fuels for electricity, heating and transportation produces green house gas emissions and pollution accelerating global warming
Photovoltaic solar panels can be connected in parallel to increase the current and therefore power output of a pv array. The current outputs of the panels add together but the panel voltages must be the same for maximum array efficiency. Connecting solar pv panels together of different voltage ratings is not recommended.
Photovoltaic solar panels require sunlight (irradiance) to generate power so understanding how to connect solar panels in series strings is important. Not everyone can purchase the same model solar panel so wiring different wattage solar panels in series will increase the voltage but reduce the current and power output. Series connected photovoltaic panels can be used to charge batteries, operate motors, or to power any number of electrical loads as the output voltage is higher compared to a single panel
Eco-friendly ways of garden watering and tips to help care for both your lawn and the environment at the same time. While gardening is a relating and enjoyable part of owning a home, it is by nature an eco-friendly activity as well. Installing rainwater harvesting barrels and butts will not only save on water, but also prevent erosion and flooding. Waste water can be used to give your garden and lawn a soaking during the coolest part of the day, allowing the water to seep into the ground before it evaporates
Measuring the output power of a solar panel, cell or array gives a better understanding of the systems power performance. One of the main disadvantages of solar panels as a renewable energy device is their lack of output power when there is no sun. The performance of photovoltaic solar panels can be determined by measuring the relationship between the panels voltage, current, and therefore power output under different meteorological conditions to determine the exact amount of electrical power available from a particular solar panel
Understanding batteries and how we can use them in an off-grid or stand alone photovoltaic storage system is important for ensuring a long service life. Batteries convert chemical energy into electrical energy and vice versa, so deciding on what battery to use, or how many batteries you will need, depends on the power and capacity requirements of your solar energy application as well as what kind of deep-discharge and recharge cycling rate the batteries will be subjected to.
Low pressure micro hydro power scheme is another type of hydropower technology which uses low-pressure, low-head turbines to generate electricity without the need for dams or water impoundment. Micro hydro power is another renewable energy source with a low environmental impact and having several advantages over the use of fossil fuels as it is a non-polluting, renewable resource causing minimal environmental disruption to both the river and the native ecology.
Bypass diodes are a must for any photovoltaic solar panel as they protect the panel from overheating when shaded by trees, leaves or debris. When one solar cell of a panel becomes shaded while the other solar cells around it are illuminated by sunlight, hot spots can be created leading to overheating and eventual destruction of the affected shaded cell. A bypass diode is commonly placed on sub-strings of the photovoltaic panel usually one diode per 15 to 20 photovoltaic cells to maintain the load current delivery of the panel
