Easy PV is a free solar PV design tool, built by Midsummer, the UK renewables distributor. Its strength is design: 2D and 3D roof design, automated stringing, structural checks, and a kit list you can order from a Midsummer trade account. Its paid Pro tier adds CRM integration, e-signing and DNO applications through ENA Connect Direct.
Payaca is the system the whole job runs on: CRM, proposals, scheduling, the field app, DNO applications via ENA Connect, MCS handover documentation, invoicing and payments on one project record, across solar, heat pumps, batteries and EV chargers. The two connect, so an Easy PV design lands on the Payaca project. Here's how they compare for a UK install business.
The short answer
Easy PV is a free solar design tool. Payaca is the system the rest of the job runs on. If you design in Easy PV, connect it to Payaca: start the Easy PV project from the Payaca job and pull its files and kit list back in, and the pipeline, schedule, DNO application, MCS handover pack and invoicing carry on around it.
- Payaca is best for clean tech install businesses running solar, heat pump, battery and EV charger jobs end to end, who want design, compliance filings, scheduling and invoicing on one project record.
- Easy PV is best for solar PV businesses that want a free, deep design and specification tool with Midsummer trade purchasing built in, plus DNO applications through ENA Connect Direct on the paid Pro tier, and run the rest of their operations in other tools.
- Payaca publishes its pricing: Growth, the standard plan for established install businesses, is £1,199/month. Current plans and eligibility are on the pricing page. Easy PV is free to use for design and quoting, with a paid Pro tier for team and CRM features and a bespoke Enterprise option.

How the two fit together
Design in Easy PV, run the job in Payaca. Connect Easy PV in Payaca's settings and it appears on each project's Design tab, where you can pull the design files and kit list into the project, next to the proposals, the schedule, the DNO application, the MCS handover pack and the invoice.
Switching from Easy PV
You don't have to leave Easy PV. Keep designing there and connect it to Payaca, so each design and kit list lands on the job.
What moves is everything you've been running around it. Customers, contacts and jobs kept in spreadsheets or another CRM come across from a CSV export, loaded through our import tooling and placed at the right stage of your pipeline.
Growth and above include guided onboarding: we map your workflow, migrate your data and train your team, for a one-off £1,500.
Which is right for you?
Choose Payaca if
- You run solar, heat pump, battery or EV charger jobs, not just solar PV
- You want the pipeline, schedule, field team, compliance and invoicing on one record
- DNO applications via ENA Connect, filed and tracked from the job, matter to you
- You design in Easy PV and want the design to flow into the job
Consider Easy PV if
- Your main need is solar PV design, specification and quoting
- You buy from Midsummer and want trade pricing and ordering built into the design
- You already have separate tools for CRM, scheduling, invoicing and compliance filings
Questions
What's the main difference between Payaca and Easy PV?
Easy PV is a solar PV design and specification tool: it designs the array, sizes the strings, checks the structure, and generates the kit list and quote. Payaca is the system the whole job runs on: the CRM, the proposals, the schedule, the field app, the DNO application, the MCS handover pack and the invoice, on one project record, across solar, heat pumps, batteries and EV chargers.
Can I use Easy PV and Payaca together?
Yes. Payaca has a native Easy PV connection (UK accounts): once connected, Easy PV appears on the project's Design tab and you can start the Easy PV project from the Payaca job and pull its files and kit list back into the project, so the design and the rest of the job live in one place. Glow, Payaca's own solar design, is also available in limited release.
Which handles MCS and DNO compliance?
They handle it at different points in the job. Easy PV's compliance output sits with the design: MCS-compliant reports and self-consumption modelling and automatic DNO forms, and its help centre says the paid Pro tier submits DNO applications and commissioning details through ENA Connect Direct. Payaca files DNO applications via ENA Connect from the job record, polls for approval in the background, and produces the MCS handover documentation alongside the commissioning and payment stages of the same project.
How do the pricing models compare?
Easy PV is free to use for design and quoting, with a paid Pro tier for team and CRM features and a bespoke Enterprise option. Payaca publishes its pricing on the pricing page, with Growth as the plan for established install businesses.
Which is better for running a growing installation business?
If your bottleneck is design, Easy PV is free to try. If your bottleneck is everything after the design, the pipeline, the schedule, the field team, the compliance paperwork and getting paid, that is what Payaca runs. In practice the strongest setup for many UK solar businesses is Easy PV for design, connected into Payaca for the job.
