The high AC and DC voltages have the advantage that line losses can be reduced almost everywhere in the system. Firstly, in the inverter, which forms the part of efficiency gain, and secondly the cable losses in the PV installation, which will be significantly lowered. In addition, the installation costs for cabling and the associated costs are reduced.
Our modular system scales easily for distributed loads, such as irrigation pumps on different parcels of land, to large, centralized loads for commercial, industrial, and utility customers.
Panel-level monitoring is a new and valuable weapon for array owners and O&M companies to improve financial performance and reduce risk in owning and operating large-scale solar arrays. The accuracy and insight from this new technology, coupled with intelligent Cloud-based analysis and diagnostics, bring many opportunities to improve energy output and improve efficiency in O&M activities.
We believe that system owners and installers should take an active role in understanding how their system is performing and that basic web based monitoring should be free and flexible. Adhering to this philosophy, we have designed the ZigBee based monitoring solution for the PV Powered HE string inverter to make string inverter performance monitoring fast, easy, simple, reliable and flexible.
This new type of architecture has inherent cost and reliability advantages over microinverters: it uses fewer critical components than microinverters, its easy installation and connection to the grid allows for reduced installation and maintenance costs and its connection to the module at a cellular level means the performance and cost of the solar module can be optimized.
The SolarTie System was designed to lower the Levelized Cost of Electricity (LCOE) for utility-scale solar power plants. A great deal of attention is being given to reducing the LCOE, which defines how much the energy produced really costs.
Many of the cutting edge thin-film technologies require rare elements that are a finite resource already in short supply. There simply is not enough material on the planet to make these devices for worldwide consumption.
If some panels go bad, you need panel level monitoring to o find the bad panels. But most systems monitor power at the system level, but as Google found out, that is that useful for detecting catastrophic failure, but not much else.
Photovoltaics is without doubt the most direct way of taking advantage of solar energy. When using photovoltaics, however, the efficiency of the various systems, and the feed-in tariffs to be expected should be kept in mind. On the one hand, the capacity of the solar modules used is important - on the other hand, the way in which these modules are used has considerable influence on their cost effectiveness.
Generally Dual-axis trackers are more accurate in pointing directly at the sun which is usually the brightest spot in the sky, however, Dual axis comes at the price of higher complexity and lower reliability ( more down time and more maintenance) than single axis.
Power generation systems have hundreds of applications. This article will focus on portable generators in specific and a range of their applications and sizing considerations in general. The intent is to address the frequently-asked questions, "What will this generator run?", "For how long?", and "Will it run my house?" Those questions usually have to be answered with the question, "What do you want (need) to run?" which defines the application.
A pre-laminate that combines ETFE frontsheet and EVA encapsulant, features all the performance benefits of both with improved production efficiencies, including reduced wrinkles and precise alignment. In addition, it can help module manufacturers achieve lower systems cost with reduced packaging and shipping costs.
Due to its stability, chemical purity, transmissivity to light, and heat resistance, quartz has for many years been vital to the production of semiconductors for the electronics industry. The material is virtually inert, very durable and will withstand the high temperatures associated with semiconductor fabrication and testing.
The "The US Solar PV Backsheet Market - Industry Trends and Opportunity Analysis to 2015" report provides market analysis and volume forecasts up to 2015 in the US. The report contains detailed analysis of PV backsheets installed, pricing, market revenues, share of imports and exports, backsheet demand based on domestic module production, lead time analysis and key product analysis.
Solar is one of the most talked-about alternative energy sources in the world today. Enough energy comes from the sun in one hour to power the global population for a year. Even though the amount of sunlight varies around the world, sunlight is a totally renewable resource, unlike oil, coal and natural gas. As long as life exists on the earth, sunlight will play a role.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
