SOLAR PV ENGINEERING DESIGN CONSULTANCY
Delivering a Customer-Driven Experience
Solar Energy California• 2151, Nectarine Drive, Santa Rosa, CA 95404, USA
ABOUT US :
We are a team of experienced engineerswho target on helping you with your designneeds in solar photovoltaic systems.
SERVICES OFFERED
SOLAR LAYOUT/SITE PLAN
Our solar layouts arehighly detailed and typicallyready for permitting. Weperform detailed shadinganalysis. We take intoconsideration OSHA safetyoffsets and other fire andcode requirements during theinitial design.After performing detailedshading analysis, weoptimize panel placement,azimuth, row offset and tiltangle to maximize energyproduction. Our designsare basedaround the panels, rackingand inverters that youspecify.
SOLAR LAYOUT/SITE PLAN
On your request, we cansuggest the best quality,lowest cost hardware basedon our experience. Aftermaximizing the layout,we can determine systemsize, number of panels, sizeof inverter and rackingrequirements. We alsospecify all major hardware onthe drawing provided.For EngineeringCompanies, EPCcontractors, PPA andArchitects we shall be glad toput the layouts on yourbranded drawing format.
ENERGY MODELLINGWe use all the commerciallyavailable software packages,however we always recommendthat PVsyst be used, since thishas become the defaultstandard in the industry.We don’t recommend PVWattsas it has been known to beinaccurate which may causeproblems with predictingenergy and providing energyguarantees. It’s not only thesoftware, it’s the data andassumptions you put in!Just because someone knowsPhotoshop, it does not makethem an artist! Assumptions onpanel soiling, snow conditions,ambient temperature, wind,panel cleaning schedule, paneldegradation, and electricallosses are often overlooked andresult in poor modelling.
Using our expertise, we canguide you through theproper assumptions andfind the most accurateweather data to use in yourmodelling. Being tooconservative means fewerwatts, and a higher cost perwatt on your project. Beingtoo aggressive has the riskof penalty if the project hasenergy productionguarantees. The energy inthe afternoon is worth moremoney, so we shift theazimuth from the normaldue south to maximizeproduction in the afternoon.
