FAQ
Frequently asked questions about our Solar PV Software
Solar PV design and quoting software lets utilities and installers size a photovoltaic system, model its energy yield, price it, and generate a client-ready quote — all in one workflow. Effizency combines automated PV design, battery (BESS) sizing, savings and payback calculations, and branded proposals so your sales team can quote accurate systems in minutes instead of days.
Yield is calculated with industry-standard engines — PVLib with a detailed loss diagram, or PVGIS — using long-term irradiance data, so results are auditable and defensible. As with any model, actual annual output typically varies ±5–10% year to year depending on weather, but design-stage estimates from these databases are the accepted benchmark for European projects.
Battery (BESS) sizing balances the customer's consumption profile, solar generation, tariffs, and export rates to find the storage capacity that maximises self-consumption and returns. Effizency optimises battery sizing in real time and lets you compare a PV-only scenario against PV + battery side by side, so the customer sees the financial difference clearly.
Yes. Effizency bundles batteries onto the solar PV design and calculates the combined savings, self-sufficiency, and payback in a single proposal. You can present standalone PV and PV + battery options together so the customer compares scenarios without you rebuilding the quote.
With automated building detection, panel placement, inverter single-line diagrams, and pre-configured pricing, a full design-to-quote cycle takes minutes rather than the hours a manual process needs. The back office holds your cost items and offer templates, so sales staff produce consistent, accurate quotes without engineering support on every deal.
Yes — it's built for utilities, energy suppliers, and installers who need to scale solar and storage sales across a team. A configurable back office lets product owners lock in pricing, products, and multi-tier offers (e.g. standard and premium), while sales works from a fast, guided flow with auditable results.
Payback compares the system's upfront cost against the annual savings from self-consumed solar, battery use, and export income under the customer's tariff structure. Effizency estimates the consumption profile for residential (lifestyle patterns) and C&I (NACE code, working schedule) customers — or takes your uploaded load curve — to produce a realistic savings and payback figure.
Yes. Proposals, handovers, and contracts are generated automatically from templates tailored to your brand guidelines, pulling client, technical, and financial data with no re-entry. Documents stay editable, so you get consistency and speed without losing the ability to tailor a specific offer.
