An energy audit involves the installation of an electrical load meter, which measures real-time energy usage. This data can then be used to design a system specific to the needs of the home or business. In addition to PV solar design, this can help to understand energy loads to best design efficiency upgrades for the property. Contact us to request an Energy Audit. Renewable Energy Services, Inc (RES) has the experience to create high-quality solar energy system designs, from high capacity commercial systems, to small off-grid installations.

The pinnacle of performance, LG has achieved industry-leading 21.4% cell efficiency at a fraction of the cost of comparable solar panels by other manufacturers, and backed by one of the industry's best warranties. This is the model of choice for customers who want the best performing solar panels available. This is where performance and aesthetics meet, using the same cell technology as the Neon R but in black format, for high-end homes and needing maximum energy generation and elegance. The latest from Hanwha Q Cells, using split cell technology, achieves the highest efficiency in its price class and in an attractive black format.

The Generac PWRcell is a smart energy management system that uses solar panels, lithium batteries and intelligence to manage your energy, reduce your electricity costs, and power your home or business even during outages. The system is beautifully integrated through a hybrid battery / PV inverter which is more efficient and requires less hardware than many grid-interactive energy storage technologies. It's also easily scalable to cover the energy needs of any size home or business. The PHI 3.8TM kWh 60 Amp deep-cycle Lithium Ferro Phosphate (LFP) battery is optimized with proprietary cell architecture, power electronics, BMS and assembly methods.

The graph to the left is an example of energy loads in contrast to solar production for a business which has opening hours during the daytime. This data was gathered from a client of ours. Due to the high volume of activity during the daytime, the solar panels are able to provide most of the businesses' energy needs. Extra solar production can be sold to HELCO for energy credit, or stored if batteries are installed. Your business can create additional value by reducing peak usage to eliminate utility demand charges.
