Utilities are essential expenses that can rob a business of its cash flow. A business` bottom line can become victim to the fluctuations and increases of utility costs. Bringing your energy expenses under control is an effective, yet often overlooked, method of increasing your bottom line. Businesses can improve their bottom line by utilizing solar to stabilize fluctuations in energy expenses, protect against energy market volatility, and reduce payments to utility companies.
In the earlier days, the chemistry involved in solar cell manufacturing was relatively simple, using commodity chemicals. With cell efficiencies continuously on the rise and new cell concepts slowly being introduced with increased speed of processing, precise chemical concentration control is becoming crucial to obtain consistency and more cost-effective manufacturing of solar panels. This is possible by monitoring on-line the etching bath composition, a small but genuine step forward in your competitive advantage....
Quality control to maximize efficiency is critical in the competitive photovoltaic industry. For some time solar texture has been thought to qualitatively affect solar cell efficiency. However, through large-area, 3D measurements and areal feature parameters, quantitative correlation of texture to efficiency has only recently been obtained. We now know that ISO 3D surface parameters linearly correlate with solar cell efficiency.
There is no legislation to control of the proper functioning of pyranometers used to measure solar radiation installed in the PV field.
The control can be effectively carried out with portable
instruments suitable to avoid uninstalling pyranometers set in areas normally inaccessible as placed at the side of panels.
A quick test on the field assesses whether a good maintenance is sufficient to obtain a reliable measurement of the solar radiation or if it is necessary to send radiation sensors to the manufacturer...
If waste wood is utilized, woody biomass can be a form of renewable energy that complements solar and wind. Furthermore, gasifying the wood to produce electricity is a lot cleaner than disposing via controlled burns, and has a lower carbon footprint than decomposition, since decomposition often produces methane, and reverts all of the carbon to carbon dioxide, whereas with gasification, a portion is sequestered as char-ash.
The range of supply of biogas to electricity solutions is from 10 kW to 1 MW. All the components of the solution are provided with matching capacities.
It comprises the biogas digester system of the desired capacity, gas storage, biogas cleaning system to get rid of H2S from the gas, and the biogas genset. In the digester system, one may have a pre-digester or a feed mixing chamber or both. On the post-digester side, liquid from the slurry is separated and is recycled for feed preparation. It reduces the overall...
