Biochar Energy

Biochar Energy from Biomass

Biochar is a charcoal looking carbon rich substance formed by heating organic biomass plant matter in low-oxygen conditions by a process known as pyrolysis. Biochar can be added to the soil as an amendment and fertiliser to improve soil conditions as well as the sequestation of carbon in the soil to reduce levels of atmospheric carbon dioxide. There are many biomass feedstocks suitable for biochar production but the type of biomass feedstock use in the pyrolysis process will determine the quality and efficiency of the biochar product

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

Solar Irradiance

Solar Irradiance

Solar Irradiance describes the total amount of sunlight per square meter that is available at any particular location on the Earth’s surface and is a major part in estimating the solar irradiation at a particular point required to design a sustainable energy system using photovoltaic solar panels. The performance of a solar photovoltaic panel depends on many factors, but the amount of solar irradiance in peak sun-hours during the day that the solar panels receive during the day is of major importance

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

Tidal Power

tidal power

Tidal Power takes advantage of the kinetic energy stored in the movement of the incoming and outgoing tides using tidal stream devices, as well as the daily differences between the high tide and low tide at a given location using tidal barages. Tidal power is a non-polluting technology with a great potential to generate large amounts of electrical energy as the moving sea water drives underwater turbines with current technologies based around tidal range and tidal stream devices.

Efficiency of Biomass Energy

efficiency of biomass energy

The efficiency of biomass energy depends on how effectively biomass resources can be converted into electrical power, heat and fuels using a variety of new techologies and traditional methods. Biomass energy crops are now being grown in vast quantities to produce modern forms of energy such as biofuels for transport, pellets for electricity generation as well as a wide diversity of bio-chemicals and bio-lubricants making biomass a truely versatile fuel.
