Equipment and products that enable us to use renewable energy instead of fossil fuels and conventional electricity are highly beneficial. Examples include solar thermal systems, solar electric (photovoltaic) systems, and wind turbines. Other power generation equipment, such as fuel cells and some energy storage systems (like batteries) are included here because they help us accommodate varied energy sources so that we may eventually move beyond fossil-fuel dependence.
Included here are various erosion-control products, foundation products that eliminate the need for excavation, and exterior stains that result in lower VOC emissions into the atmosphere. Fluorescent lamp and ballast recyclers and low-mercury fluorescent lamps reduce environmental impacts during maintenance and disposal of luminaires.
Mobile Solar Power manufactures portable solar-powered generators for use as quieter, more environmentally responsible replacements for portable diesel generators. These portable solar generators are comprised of polycrystalline PV panels, inverter, charge controller, and lead-acid storage batteries in a self-contained trailer made by Wells Cargo or Look, which protects all components other than the PV modules. Available in multiple models, they have maximum energy storage rangings from 15 to 37.6 kWh (627 to 1568 amp-hours) and daily power production up to 19.6 kWh. Rated output ranges from 30 to 140 amps. All models use Outback inverters, Sanyo monocrystalline PV modules and 24-volt, flooded lead-acid batteries made by IBE (with 7-year warranties). These units include inputs for AC power and conventional gasoline or diesel back-up generators, which can be operated at full power to re-charge batteries and then shut off to conserve fuel.
Diesel generators used to provide power to construction sites and other venues are noisy and require the transportation and consumption of fossil fuels, which can be problematic in environmentally sensitive or fire-prone areas. Portable photovoltaic (PV) generators can provide power with almost no jobsite impact and contain batteries that store power for use during unfavorable weather conditions.
PV generators should use “pure” or “true” sine wave power inverters, which produce power similar to that from the utility, rather than less-expensive modified sine wave power inverters, whose use could interfere with the performance of—or potentially damage—sensitive electronics, such as laptops, printers, certain cordless tool chargers, fluorescent ballasts, and equipment with variable speed motors.
