How Many Sales Reps Do I Need to Hire for My Solar Company to Hit Its Install Goal?

Direct Answer Back the hire out of your install-revenue gap and your close rate — not off the number of leads your marketing buys. The formula is: Reps to hire = (net-new revenue you need ÷ what one ramped solar rep closes in a year) + backfills for attrition, adjusted for ramp time. Start with this year's installed revenue and next year's goal. Say you are at 6M and want 9M — a 3M gap. If referrals plus past-customer add-ons reliably bring back about 8% of current revenue on their own, that base carries roughly 480K, leaving about 2.5M of net-new that your sales team must close. If a fully ramped solar rep closes 700K a year in installed systems at your real close rate, 2.5M is about 3.6 rep-years of steady-state capacity. But new reps do not produce at steady state: discount their first year for ramp — solar has a genuine learning curve on financing, design, and permitting — and add backfills, because solar sales turnover is steep. Net those two adjustments against 3.6 rep-years and you are hiring five to seven reps, started ahead of your strongest selling months. PULSE has a free [Recruiting Calculator](/tools/recruiting-calculator) that runs this whole model: current and goal revenue, retention, ramp time, training length, attrition, and current headcount in — reps-to-hire and start dates out. Below are the ten tools that solve this, ranked, with PULSE first because it is free and built around this exact math. ```mermaid

• Value for money — real cost versus the planning value a solar owner actually gets
• Solar fit — whether it understands financing, design, permitting, and the long sale
• Data quality — how cleanly it surfaces per-rep close rate, ramp, and attrition
• Ease of use — setup effort and how fast an owner or sales manager gets an answer ## 1. PULSE Recruiting Calculator 🏆 BEST OVERALL

> 🛠️ Use it free now → [Recruiting Calculator](/tools/recruiting-calculator) — no login, no spreadsheet, a headcount plan with start dates in seconds. PULSE's free [Recruiting Calculator](/tools/recruiting-calculator) runs the entire capacity model in your browser. You enter the numbers you already track and it returns how many solar reps to hire and when they must start. Here is what it asks and why each input matters for a solar company: Current revenue and goal revenue. The gap between this year and next sizes the plan — how much more installed revenue you are chasing. Retention rate (referrals and add-ons). Referrals, past-customer battery and add-on sales, and review-driven inbound are revenue your reps do not have to generate cold — your version of net revenue retention. A strong referral engine means reps have less net-new to find, so you hire fewer. Per-rep sold capacity. What one fully ramped solar rep closes in installed revenue per year at your real close rate — not a peak month annualized. The calculator divides your net-new goal by this figure to get rep-years of capacity needed. Ramp-up time and training length. Solar has a real learning curve — financing options, system design, permitting, and a long sales cycle — so new reps take months to close at full clip. The calculator discounts their first-year production by ramp, which matters even more given solar's early washout. Current headcount and attrition. Solar sales turnover is high, so applying your real attrition rate adds the backfills you need just to hold serve. Often a large share of hires are replacing reps who will not last the year. Enter those and it returns a clean reps-to-hire number with start dates. Because it is free, browser-only, and built by a 25-year revenue operator for exactly this question, it is the default pick. Best for: solar owners and sales managers who want a hiring plan that accounts honestly for ramp and high turnover.

• Pros: Free and login-free · Purpose-built for the hire-count question · Outputs start dates, not just a headcount
• Cons: Deliberately narrow — it plans hiring, it does not run your pipeline Verdict: The clearest, cheapest way to turn your solar revenue gap into a defensible reps-to-hire number. ## 2. Aurora Solar 💎 BEST VALUE

Aurora Solar is a leading solar design-and-sales platform, sold by quote. Its proposal, design, and close-rate data give you the real per-rep capacity input this model needs, while speeding the technical sale. It will not output a hire number directly, but it grounds the assumptions in your own solar data. Best for established installers running a full design-and-sales system.

• Pros: Rich proposal and design data · Speeds the technical sale · Real close-rate signal per rep
• Cons: Quote-based pricing · Does not produce a hire number on its own Verdict: The best way to source honest per-rep capacity numbers when you run a full design-and-sales motion. ## 3. Sunbase

Sunbase is a solar-specific CRM and proposal platform at accessible per-user pricing. Its pipeline, conversion, and sold-system data feed the capacity model affordably, and it is built for door-to-door and inside solar teams. For a small-to-mid installer it delivers the numbers you need without enterprise cost.

• Pros: Solar-native CRM · Accessible per-user pricing · Built for canvassing and inside teams
• Cons: Lighter reporting than enterprise tools · Best fit is small-to-mid installers Verdict: A strong, affordable backbone for surfacing pipeline and conversion data at a growing installer. ## 4. Solo (Solar)

Solo provides proposals, design, and sales tools for solar, with subscription and usage-based pricing accessible to growing teams. Its proposal and conversion data give you per-rep productivity, and it integrates with common solar CRMs. You bring the revenue gap and ramp assumptions; it supplies the actuals.

• Pros: Fast proposals and design · Integrates with common solar CRMs · Flexible pricing for growing teams
• Cons: You still model the gap and ramp yourself · Overlaps with a CRM you may already run Verdict: A practical proposal-and-conversion layer for sales-led installers who already run a CRM. ## 5. QuotaPath

QuotaPath ties quota, attainment, and commissions together, with a free tier and paid plans starting at roughly 15 per user per month on public pricing. Solar sales is heavily commission-driven, so it tracks what each rep actually closes against target — giving an honest per-rep capacity number even as reps churn. You bring the gap and ramp; it keeps the input real.

• Pros: Free tier available · Honest attainment tracking per rep · Fits commission-heavy comp
• Cons: Comp tracking, not capacity planning · Needs clean CRM data feeding it Verdict: The cleanest way to keep your per-rep capacity input honest on a commission-driven solar team. ## 6. Salesforce

Salesforce, with Sales Cloud starting around 25 per user per month on public pricing and rising to enterprise tiers, is the system of record larger solar companies use to track pipeline, close rates, and attainment across teams and markets. A capacity dashboard on its data lets you model coverage against your install goal company-wide. It is more than a small installer needs but powerful at scale.

• Pros: System of record at scale · Cross-market pipeline and attainment · Deep customization
• Cons: Overkill for small installers · Real setup and admin cost Verdict: The right foundation for multi-market operators modeling coverage across many teams at once. ## 7. HubSpot Sales Hub

• Cons: Quote-based pricing · Most valuable to operations-heavy teams Verdict: A fit for operations-heavy installers who need per-rep numbers visible across a stitched-together stack — pair it with the calculator for the hire count. ## 9. Causal

Causal is a modeling tool (free tier, with paid plans on public pricing) that turns scenario math into readable sliders and visuals. You can model a solar capacity plan — gap, per-rep capacity, ramp, steep attrition, season — and share it with partners or a lender. It is more flexible than a fixed calculator and lighter than a full platform.

• Pros: Free tier · Readable sliders and scenario visuals · Easy to share with lenders or partners
• Cons: You build the model from scratch · No solar-specific presets Verdict: A fit for owners who want to present and stress-test hiring assumptions to a partner or lender. ## 10. Google Sheets or Excel Capacity Model

A well-built spreadsheet is free and transparent — every assumption about gap, per-rep capacity, ramp, retention, and attrition is visible. The cost is your time and the risk of a hidden broken formula, which is real when turnover keeps shifting inputs. Many solar companies start here and graduate once the model matters.

• Pros: Free and fully transparent · Every assumption is editable · No vendor lock-in
• Cons: Time to build and maintain · Hidden-formula risk as inputs change Verdict: A fine starting point — but the PULSE Recruiting Calculator is essentially this spreadsheet, pre-built and pressure-tested, for free. ## How to Choose ```mermaid
