Solar Design Software
Turn energy complexity into confidence
From small residential installations to complex C&I infrastructure projects, SolarPlus is driving the future of home and business electrification.
From small residential installations to complex C&I infrastructure projects, SolarPlus is driving the future of home and business electrification.
Design, modelling and sales software for commercial and industrial, residential and off-grid solar and storage. One platform, from feasibility assessment to installation.
Price and rank hundreds of solar-and-battery sizing options against a site's real consumption and tariff, ranked by NPV, payback, IRR or self-sufficiency, so you can qualify and defend the right system in dollars before any design work.
Automated design and stringing built from real equipment datasheets, with ray-traced shade analysis, 3D site models, single-line diagrams and the electrical checks that keep a commercial system defensible.
Model generation, consumption and storage at five-minute resolution across commercial tariffs and demand charges. Size and dispatch batteries and generators for self-consumption, peak shaving and demand-charge reduction, and stack EV, load-shifting and hot-water savings on top.
Turn the modelling into a credible financial case (LCoE, NPV, IRR and lifetime cashflow), including a comparison against the cost of doing nothing. Present side-by-side proposals the decision-maker can accept and pay for online.
A built-in CRM tracks every job from enquiry to installation. Design and compliance checks, Job Safety Analysis and one-click handover manuals carry the approved design through to delivery without rework.
From 1 October, the SRES expansion lets systems up to 1 MW claim STCs at full capacity, up from 100 kW. For EPCs, that means a jump in mid-scale projects worth chasing, more tenders and sharper competition.
Join us for a free live webinar on how to turn around more tenders without adding headcount, and how to win the work with a defensible, value-stacked investment case that stands up to a CFO or investment committee. Includes a commercial site built live, from design through to a finished business case.
For C&I teams scaling up to take a bigger share before the rush.
