Parallel Connected Solar Panels

monocystalline solar panel

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.

Series Connected Solar Panels

monocystalline solar panel

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

Water Sprinkler

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 Power of a Solar Panel

measuring the power of a solar panel

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

Trojan T105RE Battery

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

Micro Hydro Weir

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 Diode

Solar Panel Shading

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

DIY Solar Power System

diy solar power

DIY solar power systems do not have to be large home built constructions as there are plently of plug ‘n’ play home solar kits available for all sorts of applications. Designing your diy solar power kit or system requires you to make a few decisions first, such as, do I want a grid-connected or an off-grid connected system, do I want or need storage batteries as part of my system, and what are my energy requirements or daily consumption. Making solar generation from a diy kit a reality helps reduce the amount of electricity you pull from the utility grid

Wind Power and the Environment

wind power environment

Wind power and the environment continues to be a discusion as we use the renewable energy sources available within the environment to power our lives. While wind power is a clean, sustainable and accepted alternative to burning fossil fuels, the environmental imapact of wind power on wildlife and their natural habitats must be taken into consideration when siting a new wind farm. Wind farms built for the production of electricity have the potential to impact the natural and urban environment affecting birds, bats and other fauna and flora at a specific site
