Solar Projects Oceanside CA

Our Solar Projects

Cleantech Energy Solutions Inc has completed solar projects throughout Oceanside CA and across San Diego County since 2007. With industry roots dating back to 1984, our experience spans residential installations, commercial systems, energy storage integration, system repairs, and temporary removal for roof replacement.



Every project reflects our commitment to technical precision, regulatory compliance, and long term performance. California solar installation requires careful planning around utility rate structures, Net Energy Metering policies, and strict building and electrical standards. Our completed projects demonstrate our ability to navigate these requirements while delivering dependable energy solutions.

Residential Solar Installation Projects

Homeowners throughout Oceanside and surrounding communities trust Cleantech Energy Solutions Inc to design and install photovoltaic systems that align with their energy usage and financial goals.

Our residential projects typically include:

  • Custom system sizing based on historical usage
  • Drone based roof surveys for accurate design
  • Code compliant mounting and electrical installation
  • Utility interconnection coordination
  • Monitoring setup and performance verification

Each home presents unique considerations, including roof orientation, structural capacity, shading conditions, and electrical panel configuration. Our drone survey process allows us to collect precise measurements and optimize panel placement for maximum production.



We design residential systems with current California Net Energy Metering structures in mind, helping homeowners increase self consumption and protect long term savings.

Commercial Solar Projects

Businesses across San Diego County face rising operational costs due to increasing electricity rates. Commercial solar projects provide long term cost stability and reduced grid dependence.

Our commercial installations require detailed coordination, including:

  • Load analysis and system sizing
  • Structural evaluation of commercial roofing
  • Compliance with local permitting offices
  • Utility interconnection management
  • Scheduling to minimize business disruption

We work closely with property owners and facility managers to ensure that installation timelines align with operational needs.



Commercial projects often include expanded electrical infrastructure and larger scale system design, requiring experienced technical oversight.

Solar Plus Storage Projects

As California transitions toward time of use billing and evolving Net Energy Metering policies, many of our recent projects include energy storage integration.

Solar plus storage projects allow property owners to:

  • Store excess daytime production
  • Reduce exposure to peak utility rates
  • Maintain backup power during outages
  • Increase energy independence

Battery systems are carefully configured to support selected circuits and manage daily load patterns. Our team ensures proper electrical planning and compliance with current California fire and safety standards.

Projects involving energy storage require thoughtful design to balance cost savings with backup reliability. Our portfolio reflects successful integration of battery systems with both new and existing solar arrays.

System Repair and Restoration Projects

In addition to new installations, we have completed numerous system repair and restoration projects for clients whose original installers are no longer in business.

These projects often involve:

  • Inverter replacement
  • Monitoring restoration
  • Wiring corrections
  • Performance diagnostics
  • Code compliance updates

Repair projects require careful troubleshooting and a thorough understanding of legacy system designs. Our experience across multiple equipment brands and installation styles allows us to adapt to diverse configurations.



By restoring system performance, we help property owners regain expected energy savings and maintain compliance with California standards.

Temporary Removal and Reinstallation Projects

Roof replacement is common for properties with aging roofing materials. We regularly complete temporary solar removal and reinstallation projects to support roofing upgrades.

These projects include:

  • Safe system shutdown and disconnection
  • Careful removal and storage of panels
  • Inspection of mounting hardware
  • Code compliant reinstallation
  • Final system testing and commissioning

Temporary removal projects demand coordination with roofing contractors and strict adherence to updated building codes. Our experience ensures that systems return to operation safely and efficiently.
