Solar Panel Cost Calculator App
Talk to the Team
Mestertaket Solar needed to professionalise their sales process by replacing manual estimation methods with a scalable digital platform. They faced significant pressure to provide accurate, real-time solar quotes that accounted for complex roof variables and government subsidies. The objective was to empower their sales experts with a robust tool that could streamline operations, improve quote precision, and support rapid business expansion.
WebMob Technologies delivered a comprehensive solar panel cost calculator platform designed to bridge the gap between solar suppliers and sales personnel. By integrating advanced geographic data and real-time financial logic, we provided a solution that automates complex estimation workflows. The platform features a multi-tenant architecture, allowing the client to manage multiple distributors through a centralised admin panel.
The client struggled to scale their solar sales operations due to fragmented data, complex subsidy calculations, and the inability to manage multiple distributors within a single, unified system.
Geographic Data Integration
Integrating geographic services into a solar estimation workflow was highly complex, preventing the client from providing accurate, location-specific quotes for varying roof types.
We integrated the NORKART API to enable dynamic map views, allowing sales experts to pull precise geo-data and roof specifications directly into the estimation process.
Complex Financial Estimation
The client lacked a reliable way to calculate costs that accounted for fluctuating panel types, accessories, and ENOVA subsidy adjustments in real-time.
We engineered a smart, real-time calculator that automatically updates cost figures based on live filter changes, ensuring every quote is accurate and subsidy-compliant.
Roof-Specific Accuracy
Inconsistent roof data led to imprecise solar panel cost estimates, which hindered the sales team's ability to close deals effectively.
We implemented a detailed map view system that captures specific roof details, providing the necessary data points to generate precise, professional solar system estimates.
We engineered a multi-tenant system that assigns unique subdomains to each distributor. This enables the client to manage firm-distributor relations and monitor all sales activity in real time.
This central hub allows the client to manage custom branding and product listings for every distributor. It provides the necessary tools to generate accurate estimates and close deals.
We developed a comprehensive tracking system that logs order history and performance metrics. This allows the client to maintain data accuracy across all client-specific solar projects.
This inventory management feature allows the client to update pricing and stock levels for panels and inverters. It ensures sales personnel always have access to current product data.
We integrated the NORKART API to provide precise geographic data and map services. This enables the client to perform accurate site assessments for solar rooftop installations.
We implemented a secure access protocol that restricts system usage to authorised personnel. This protects sensitive order details and ensures only genuine users access the calculator.
This dynamic engine calculates solar costs by applying ENOVA subsidies and real-time product pricing. It provides the client with an automated, reliable method for generating final quotes.
We integrated Calendly to streamline the meeting scheduling process between sales experts and clients. This feature provides the client with valuable insights into their sales pipeline.
