Solar & Energy Storage Systems

About Photovoltaic (PV) Solar Installation Solutions

Adding photovoltaic (PV) solar to operations can mitigate energy costs by offsetting kWh used onsite, whether by irrigation pumps, chillers, processing equipment, cow comfort components and milk processing equipment, “upgraders” used to clean digester biogas, or other machinery.

Solar PV systems can be located on open ground, on facility rooftops, and in parking lots. Solar carports can be used to charge electric vehicles. With solar becoming more affordable and electricity rates rising, combined with favorable federal tax incentives, customers can yield high energy savings for 25 years or more.

Associated GHG Emissions Reduction

GHG emissions reductions vary depending on the size of the solar PV installation. As a rule of thumb, every ~1562 kWh offset by renewable generation equates to a decrease of 1MT CO2e based on the assumption that the energy supply is fossil-fuel based.

About Energy Storage & Microgrid Solutions

Battery energy storage systems (BESS) can be deployed as stand-alone technology to support onsite loads and provide backup power during outages or high-value time-of-use periods. Paired with solar, energy storage allows for energy offset in the hours your system cannot produce. Primarily, this reduces energy costs, but it can also shave energy demand and provide stability when grid energy supply is unreliable, such as during blackouts or PSPS (Public Safety Power Shutoff) events. 

A microgrid is a local power source, either interconnected to the utility or operating independently of a utility, that would allow for continuous power offset by using at least two power generation sources. Microgrids can incorporate solar plus energy storage with control systems for precise energy management on site. This can be critical for operations that cannot sustain a shutdown or experience significantly reduced productivity when power is unreliable.

Key Benefits:

  • Reduce demand charges
  • Reduce energy costs via rate and time-of-use (TOU) arbitrage
  • Offset usage during non-solar hours
  • Resiliency through a backup power supply
  • Pointed management of energy specific to site needs
  • Independent power supply (in the case of microgrids)

In Our Market

Our team members have led the deployment of 150+ megawatts (MW) of solar generating and energy storage capacity. We have self-performed the installation of over 180 solar PV systems ranging from 50 kWDC to 6.5 MWDC using various racking, inverter, and module technologies.

We at CalCom Energy are experts in the field of NEMA. We were one of the first solar firms to interconnect a solar project under the NEMA tariff and the first solar firm in California to interconnect a PV system under NEMA with a new primary service (“no-load”) meter.

We continue to influence the solar industry from the inside; CalCom Energy’s Interconnection & Utilities Relations Manager is also the interconnection chair for California Solar + Storage Association (CALSSA, formerly CALSEIA), and we advocate for clean energy policies from the utilities that benefit our clients throughout California.

Key Capabilities

EPC and Ancillary Services

Our service offerings include design, engineering, procurement, and construction of solar and energy storage systems, asset management, and post-construction energy services that provide additional power and monetary savings over the life of the system.

Utility Interconnection

Utility interconnection and related matters are specialties of ours. Working closely with the California utilities, CalCom Energy successfully negotiated a mechanism for lowering interconnection costs on commercial and industrial PV systems, resulting in cumulative savings to our clients of $13,000,000+.

Analysis for Optimal Value of Solar

CalCom Energy always designs PV systems for optimal value. We conduct an internal analysis to determine the optimal value of PV energy by overlaying a specific energy load and usage profile with the applicable utility rate schedules and tariff parameters and design our systems to maximize ROI.
